This paper focuses on the examination of stable and unstable geometrical structures of thin-shell wormholes constructed from Henneaux–Martinez–Troncoso–Zanelli black holes through the Visser cut-and-paste approach. We use the Israel thin-shell formalism for evaluating the stress–energy tensor components of the matter distribution near the wormhole throat. Equations of state, specifically the phantom-like and generalized Chaplygin gas model for exotic matter, are used to conduct an extensive investigation into the stability of the thin-shell. The radial perturbation around the equilibrium throat radius is also considered to explore the stable configuration for specific values of physical parameters. Our results show that the stable zones of these thin-shell wormholes increase as the scalar field parameter ℰ approaches −1. This study gives light on the behavior and dynamics of these wormholes throw light on their potential stability and lead the way for additional theoretical physics research. [ABSTRACT FROM AUTHOR]

The concept of orbital angular momentum (OAM) of light has not only advanced fundamental physics research but also yielded a plethora of practical applications, benefitting from the abundant methods for OAM generation based on linear, nonlinear and combined schemes. The combined scheme could generate octave-separating OAM beams, potentially increasing the channels for optical communication and data storage. However, this scheme faces a challenge in achieving high conversion efficiency. In this work, we have demonstrated the generation of multiple OAM beams at both fundamental frequency and second harmonic (SH) wavelengths using a three-dimensional forked grating array with both spatial χ(1) and χ(2) distributions in a lithium niobate nonlinear photonic crystal platform. The enhancements of the fundamental and SH OAM beams have been achieved by employing linear Bragg diffraction and nonlinear Bragg diffraction, respectively, i.e., quasi-phase matching. The experimental results show that OAM beams with variable topological charges can be enhanced at different diffraction orders via wavelength or angle tuning, achieving conversion efficiencies of 60.45 % for the linear OAM beams and 1.08 × 10−4 W−1 for the nonlinear ones. This work provides a promising approach for parallel detection of OAM states in optical communications, and extends beyond OAM towards the control of structured light via cascaded linear and nonlinear processes.

The objectives of NSTX-U research are to reinforce the advantages of STs while addressing the challenges. To extend confinement physics of low- A, high beta plasmas to lower collisionality levels, understanding of the transport mechanisms that set confinement performance and pedestal profiles is being advanced through gyrokinetic simulations, reduced model development, and comparison to NSTX experiment, as well as improved simulation of RF heating. To develop stable non-inductive scenarios needed for steady-state operation, various performance-limiting modes of instability were studied, including MHD, tearing modes, and energetic particle instabilities. Predictive tools were developed, covering disruptions, runaway electrons, equilibrium reconstruction, and control tools. To develop power and particle handling techniques to optimize plasma exhaust in high performance scenarios, innovative lithium-based solutions are being developed to handle the very high heat flux levels that the increased heating power and compact geometry of NSTX-U will produce, and will be seen in future STs. Predictive capabilities accounting for plasma phenomena, like edge harmonic oscillations, ELMs, and blobs, are being tested and improved. In these ways, NSTX-U researchers are advancing the physics understanding of ST plasmas to maximize the benefit that will be gained from further NSTX-U experiments and to increase confidence in projections to future devices.

The Center for Axion and Precision Physics Research at the Institute for Basic Science in Republic of Korea is home to multiple active axion search experiments using cavity haloscopes that operate within the frequency range of 1–6 GHz. The haloscopes convert axions to photons, resulting in an output power of about 10 - 24 –10 - 22 W. To detect such a small signal amidst noise, quantum-limited noise amplifiers and ultra-low-temperature environment (a few tenths of mK) are required for all critical readout components to minimize noise from all active and passive lossy components. Our primary objective is to achieve the highest possible scanning-frequency speed, which includes the time for maintenance and system calibration. This paper presents the development and operation of low-noise amplifiers for haloscope experiments targeting different frequency ranges and provides design, operational, and performance details of the amplifiers.

Parity‐time (PT) and anti‐parity‐time (anti‐PT) symmetries have provided important guiding principles in the research of non‐Hermitian physics. However, realizations of anti‐PT symmetry in photonic systems usually rely on optical nonlinearities and indirect‐coupling approaches. Here, they apply the channel interference principle mediated by synthetic gauge‐flux biasing in open‐cavity systems to construct anti‐PT symmetries. It is shown that a specific π‐flux biasing into a looped‐resonator array can force a frequency degeneracy between pairwise Bloch modes therein. By further coupling the array into two external waveguides with tailored positions of ports, the system near the degeneracy point can be described by an anti‐PT‐symmetric Hamiltonian. When a real gauge‐flux detuning is introduced, the system undergoes a spontaneous transition between anti‐PT and anti‐PT‐broken phases, through which the two extreme cases of complete channel‐drop tunneling and complete tunneling suppression can be switched. Finally, by superimposing a PT‐symmetric term onto the anti‐PT‐symmetric Hamiltonian via applying an imaginary gauge‐flux biasing, extreme channel‐drop amplifying effects can be further realized by exciting the "lasing" mode under the critical‐coupling condition. The work bridges the physical connection between synthetic gauge field and anti‐PT symmetry. This paradigm may also find many applications from optical routing, and switching to buffering and amplifying on a chip–scale platform. [ABSTRACT FROM AUTHOR]

In the course of the program for the development of high-resolution photographic materials for research in neutrino physics, the possibility of obtaining a nuclear emulsion with a resolution that exceeds the known materials by 5 times has been shown. The sensitivity in such materials is maintained at a high level, sufficient for the registration of nuclear radiation. With an increase in the concentration of silver halide up to 80 wt %, nuclear photographic materials can be used to solve many physical problems. [ABSTRACT FROM AUTHOR]

Nonlinear pulse compression techniques have been applied widely in the pursuit of ultra‐intense laser pulse with extremely high pulse energy (≈mJ) and extremely short pulse duration (≈sub‐10 fs). Although postcompression techniques using dispersive gratings or chirped mirrors have achieved 1 TW few‐cycle pulses, further increasing of the pulse intensity is limited by the damage threshold of dispersive optics, especially when self‐focusing and ionization in the propagation medium are considered. To overcome such limitations, ultrashort pulses self‐compression techniques without vulnerable dispersive optics have been explored in the past two decades. In this paper, the latest advances in these techniques will be reviewed with a discussion on the progress of various experimental approaches as well as their potential applications and roles in generating extremely intense optical fields for strong‐field physics research.

Laser pulse amplification by a high-pressure CO2 amplifier in the long-wave infrared (LWIR) spectral range is a feasible technology for strong-field physics research. Crystals such as ZnGeP2 (ZGP) have high nonlinear coefficients and transmittance in the LWIR region, with spectral widths of generated pulses closely matching the gain spectrum of high-pressure CO2 amplifiers. Therefore, ZGP optical parametric oscillation (OPO) may allow higher-efficiency energy extraction in amplifiers, improving the output characteristics of LWIR amplification systems. In this study, the gain measurement of ZGP OPO pulses amplified by a high-pressure CO2 amplifier was carried out for the first time. Single-detector acquisition was utilized to achieve a unified sensor responsivity, and a laser signal-triggered function generator was used to synchronize the seed pulse and amplifier. Six-pass amplification was performed successively, yielding an amplification factor of 4.5 for the peak power and a maximum coefficient of 0.42% cm−1 for the small-signal gain. The gain and loss effect during small-signal amplification were discussed. The potential capability of acquiring ultra-short pulses with ZGP OPO pulses was also explored with the FFT function of MATLAB software. [ABSTRACT FROM AUTHOR]

Free energy calculation is fundamentally important in the research of physics, chemistry, and materials. Thermodynamic integration is the most common way to estimate free energies. In the research, we proposed a unified approach using atomic simulations to calculate the free energies of liquid and defective crystals. The new approach is based on thermodynamic integration using two alchemical pathways. Softcore potentials are developed for three-body interatomic potentials to realize the alchemical pathways. Employing the new approach, the free energy of the liquid can be calculated without requiring another reference system. The free energy of the defective crystal can be calculated directly at high temperatures. It avoids the singularity at the integration endpoint caused by the defect diffusion, which is a serious problem in the widely used Einstein crystal method. In addition, the new approach can capture the whole free energy of the defective crystal including the contribution of anharmonic and configurational entropy, which are particularly important at high temperatures. The new method is simple yet effective and can be extended to different materials and more complex liquid and defective crystal systems. [ABSTRACT FROM AUTHOR]

This overview provides a comprehensive insight into Callio Lab, a versatile multidisciplinary research platform, by describing the events and actions that have led to the development of the project-based, pay-by-service approach to organizing and economically running the research activities, a mandatory approach for a platform operating without governmental funding. The research platform has a maximum depth of 1.4 km underground, equivalent to approximately 4,100 m of water equivalent (m.w.e.). The flat-overburden mine configuration of Callio Lab minimizes cosmic-ray background interference, making it an ideal setting for low-background experiments, particularly in neutrino and dark matter research. The main-level galleries, with dimensions up to 12 m wide, 30-40 m long, and 8 m tall, provide ample space for research activities, with the potential for even more extensive galleries based on Laguna design studies. Callio Lab has a history with several small and medium-scale cosmic ray and low-background experiments. This overview highlights the site's inherent characteristics, revealing promising opportunities for high-energy and applied physics research and applications across various scientific domains.

Collapsing different category numbers within attitudinal measurement on learning and instruction can be an option of physics education research (PER) scholars while interpreting categorical responses from participants. Psychometric evaluation of the different category numbers, however, has inconclusive results to date. Item response theory (IRT) offers psychometric framework at the item level that has been approached in this study to explore psychometric properties of five different number of categories. One thousand artificial data within five number of categories were generated based on the underlying marginal distribution and the inter item correlation matrix. Statistical parameters [item estimates and test information functions (TIFs)] from Graded Response Model (GRM) were employed to describe the psychometric behaviors of the studied category numbers. Our findings demonstrated that the discrimination index among the five category numbers remained constant. Global fit indices had no distinguishable information to differentiate the varying category numbers. Based on the item location and TIF, our results confirmed previous works that more information will be raised by the greater number of categories. The implication intended by this study should offer a key recommendation for a case from attitudinal measurement on the PER community or even beyond the psychometric field. [ABSTRACT FROM AUTHOR]

Research framed around issues of diversity and representation in STEM is often controversial. The question of what constitutes a valid critique of such research, or the appropriate manner of airing such a critique, thus has a heavy ideological and political subtext. Here, we outline an attempt to comment on a paper recently published in the research journal Physical Review – Physics Education Research (PRPER). The article in question claimed to find evidence of 'whiteness' in introductory physics from analysis of a six-minute video. We argue that even if one accepts the rather tenuous proposition that 'whiteness' is sufficiently well defined to observe, the study lacks the proper controls, checks and methodology to allow for confirmation or disconfirmation of the authors' interpretation of the data. The authors of the whiteness study, however, make the stunning claim that their study cannot be judged by standards common in science. We summarize our written critique and its fate, along with a brief description of its genesis as a response to an article in which senior officers of the American Physical Society (which publishes PRPER) explained that the appropriate venue for addressing issues with the paper at hand is via normal editorial processes.

Northwest Medical Physics Center (NMPC) is a nonprofit organization that provides clinical physics support to over 35 radiation therapy facilities concentrated in the Pacific Northwest. Although clinical service is the primary function of NMPC, the diverse array of clinical sites and physics expertise has allowed for the establishment of structured education and research programs, which are complementary to the organization's clinical mission. Three clinical training programs have been developed at NMPC: a therapy medical physics residency program accredited by the Commission on Accreditation of Medical Physics Education Programs (CAMPEP), an Applied Physics Technologist (APT) program, and a summer undergraduate internship program. A partnership has also been established with a major radiation oncology clinical vendor for the purposes of validating and testing new clinical devices across multiple facilities. These programs are managed by a dedicated education and research team at NMPC, made up of four qualified medical physicists (QMPs). The education and research work has made a significant contribution to the organization's clinical mission, and it has provided new training opportunities for early‐career physicists across many different clinical environments. Education and research can be incorporated into nonacademic clinical environments, improving the quality of patient care, and increasing the number and type of training opportunities available for medical physicists.

This paper introduces a method for characterizing the current noise of commercial constant-current sources (CCSs) using a free-induction-decay (FID) type optically pumped rubidium atomic magnetometer driven by a radio frequency magnetic field. We convert the sensitivity of the atomic magnetometer into the current noise of CCS by calibrating the coil constant. At the same time, the current noise characteristics of six typical commercial low-noise CCSs are compared. The current noise level of the Keysight model B2961A is the lowest among the six tested CCSs, which is 36.233 ± 0.022 nA/Hz1/2 at 1–25 Hz and 133.905 ± 0.080 nA/Hz1/2 at 1–100 Hz. The sensitivity of the atomic magnetometer is dependent on the current noise level of the CCS. The CCS with low noise is of great significance for high-sensitivity atomic magnetometers. This research provides an important reference for promoting the development of high precision CCS, metrology, and basic physics research. [ABSTRACT FROM AUTHOR]

The availability of pulsed x rays on short timescales has opened up new avenues of research in the physics and chemistry of shocked materials. The continued installation of shock platforms such as gas guns and high power lasers placed at beamline x-ray facilities has advanced our knowledge of materials shocked to extreme conditions of pressure and temperature. In addition, theoretical advancements have made direct correspondence with high-pressure x-ray experiments more viable, increasing the predictive capability of these models. In this paper, we discuss both recent experimental results and the theory and modeling that has been developed to treat these complex situations. Finally, we discuss the impact that new platforms and increased beam time may have on the future direction of this field. [ABSTRACT FROM AUTHOR]

In this study, Higgs production processes, Higgsstrahlung and vector boson (W and Z) fusion processes, are investigated for four different future lepton colliders (CEPC, ILC, CLIC, and FCC-ee). The cross-sections for each production process and corresponding backgrounds are calculated considering the Initial State Radiation (ISR) and Beamstrahlung (BS) effects. Various cuts and the b-tagging method are used to reduce the background. Finally, the number of events for each collider is determined, and significance calculations are performed. In our calculations, high event numbers are obtained for all four colliders for the Higgsstrahlung, W , and Z fusion process. This shows that electron–positron colliders will play an important role in future Higgs physics research. [ABSTRACT FROM AUTHOR]

Friedrich Dürrenmatt and Hans Magnus Enzensberger are universal intellectuals in the sense that they are also interested in developments in the natural sciences. It is therefore not surprising that they both visited CERN independently of each other. The visit was reflected in their essayistic works, but also shows interesting connections with their fiction. The differences in their perspectives are very marked. Dürrenmatt's vision remains that of a layman, who, from a professional point of view, glides over the surface. The author views modern physics research primarily from a moral point of view, and his attitude is conditioned by the context of the moral failure of physics during the Second World War. Enzensberger, on the other hand, is an example of a man of letters who is sovereignly oriented in natural sciences. Besides the moral dimension of modern research, he is primarily interested in the aesthetic potential of scientific content. [ABSTRACT FROM AUTHOR]

A robust knowledge of physics entails deeply understanding electricity concepts such as conductivity and resistance. Understanding how circuits work is also critical for ensuring the safe use of electrical technology such as car batteries and downed powerlines. Curricular materials covering these content ideas are readily available for teachers. However, these materials rarely promote the use of research-based practices to effectively scaffold from documented authentic historical episodes of physics research to physics and the nature of science (NOS) concepts. Such practices that invoke a conceptual change approach are a crucial component of inquiry experiences that deepen students' understanding of science concepts and the NOS. The highly contextualized inquiry activity focused on Georg Ohm and electrical resistance profiled here supports teachers' use of historically accurate video vignettes of scientific developments in physics to teach Next Generation Science Standards (NGSS) based NOS and science concepts.

Ultrahigh peak-power lasers are important scientific tools for frontier laser physics research, in which both the peak power improvement and operating safety are very important. Based on spatial-chirp-induced beam smoothing in both the near field and far field, a multistage-smoothing-based multistep pulse compressor (MS-MPC) is proposed here to further improve safety and operating convenience. In the MS-MPC, beam smoothing is not simply executed in the pre-compressor or main compressor but is separated into multiple stages. As a result, important and expensive optics are directly protected in every stage. The prism-pair-based pre-compressor induces a small spatial chirp, making it both easier to achieve than the previous multistep pulse compressor and sufficient to protect the first grating directly. Furthermore, the asymmetric four-grating compressor, which serves as the main compressor, induces a spatial chirp that further smooths the laser beam, protecting the last grating. In this way, a 10 s to 100 s petawatt laser pulse can be compressed with a single laser beam using the currently available optics. Additionally, an extra beam-smoothing stage can be added before the main amplifier to safeguard the largest amplification crystal from damage. The MS-MPC can be easily integrated into all existing PW laser facilities to improve their potential compressed pulse energy and operational safety. [ABSTRACT FROM AUTHOR]

The present study intends to explore the overall research performance/engagement of the faculty members on the ResearchGate from the Physics discipline working at Indian Central Universities. The analyzed data revealed that 473 faculty members were found, but only 361 (i.e., 76.32%) have their profile on ResearchGate. Further analyses include the distribution of RG metrices which indicated that 98.89% and 98.06% of the faculty members had added at least one research item and at least one full-text research item over the RG, respectively. The findings stated that Kriti Ranjan from the University of Delhi secured highest ranking across all metrices, except followers and followings. The mean value for the Reads and Citations were found to be 27525.59 (std. dev. = 163029.86) and 1555.2 (std. dev. = 5838.76), respectively. In addition, RI Score exhibits a strong positive correlation with other RG-based metrices excluding the ‘following’. This study can be considered the only ResearchGate analyses that has included the working researchers of the Physics discipline by analyzing their research engagement and active presence over it.

Although increasing student motivation is widely accepted to enhance learning outcomes, this relationship has scarcely been studied quantitatively. Therefore, this study aimed to address this knowledge gap by exploring the effects of gamification on students' motivation and consequently their learning performance, regarding the proper application of the scientific method. To motivate students and enhance their acquisition of new skills, we developed a gamification framework for the laboratory sessions of first-year physics in an engineering degree. Data regarding student motivation were collected through a Likert-scale-type satisfaction questionnaire. The inter-item correlations and Cronbach's alpha confirmed the internal consistency of the questionnaire. In addition, the learning outcome was assessed based on the students' laboratory reports. Students participating in gamified activities were more motivated than those participating in non-gamified activities and obtained better learning results overall. Our findings suggest that gamified laboratory sessions boost students´ extrinsic motivation, and consequently inspire their intrinsic motivation and increase their learning performance. Finally, we discuss our results, with a focus on specific skills and the short- and long-term effects of gamification. [ABSTRACT FROM AUTHOR]

With the development of computational research methods and the availability of large electronic databases, interdisciplinary research in physics has boomed in recent decades. By modelling complex systems based on networks, we can study biological, social or even economic systems. Social physics (sociophysics) studies the behaviour of crowds of people, while economic physics (econophysics) tries to model economic phenomena using the methods of statistical physics. At the Hungarian Institute of Physics of Babeº-Bolyai University, under the direction of Zoltán Néda, some interesting research results on collective phenomena and complex systems have been produced in recent years. Zoltán Néda’s research area is interdisciplinarily applied statistical physics, including the statistical physics approach to social phenomena. The researcher has spoken about the nature of complex systems and their modelling methods. [ABSTRACT FROM AUTHOR]

Higher collision energies at future colliders may eventually lead to the falsification of standard fixed-order perturbation theory and linear evolutions due to nonlinear structure of QCD at small- x. New physics research works that are strictly based on accurate jet measurements will undoubtedly have this observation known as Balitsky–Fadin–Kuraev–Lipatov (BFKL) effect via angular jet decorrelations taking into account the Mueller–Navelet jets. As one of the frontier colliders, FCC-ep, has a great observation potential on parton densities through asymmetrical collisions. We aim to test the observability of azimuthal angular jet decorrelations with the recent event generators (HERWIG, PYTHIA) at the generator and detector level for FCC-ep center of mass energies s = 3. 5 TeV in proton–electron collisions. Jets are reconstructed by the anti- k T algorithm (R = 0. 5), with p T > 1 5 GeV and selected in the range of | η | < 6. Relevant pseudo-rapidity regions have been analyzed with the azimuthal-angle difference between Mueller–Navelet Jets (Δ Φ) in the pseudo-rapidity separation (Δ η) and the distributions of 〈 cos (n (π − Δ ϕ)) 〉 are presented in comparison as the result.

These properties will benefit greatly from this novel bidimensional nanomaterial. [ABSTRACT FROM AUTHOR]

Maxima software is a freely distributed computer algebra system. It is, therefore, a free alternative to systems applied to Physics research as well as to the development of digital resource for Physics teaching. In this work, one of the manners of applying Maxima to Physics teaching is presented by solving numerically the one-dimensional heat equation. With help of a tool named Draw, which allows to create GIFs directly from Maxima input, simulations of the thermic variation in a thermic conducting isolated bar which extremities are subjected to fixed arbitrary temperatures are generated. The presented examples can be used to facilitate the understanding of dynamic situations arising from the heat equation as well as the numerical method of finite differences applied to solve partial differential equations.

Terada Torahiko is known as a scientific essayist in Japan, but hardly anyone knows he was a haikai poet as well as a physicist. According to him, haikai poetry and physics are two different ways of conceiving Nature, both valid and perhaps complementary to each other. Seeing his research in physics looking for regularities in apparently irregular phenomena in everyday life, we may say his haiku haikai spirit is manifest there and that he was pioneering a new science such as the one developed later by Ilya Prigogine. His association of haiku haikai poetry and Freudian interpretations of dreams leads us to rethink the relation between science and literature. This paper examines Terada's poetics as well as his research in physics in order to see how one can associate the Two Cultures separated from each other for such a long time. [ABSTRACT FROM AUTHOR]
