1. Comment on 'Light-induced melting of competing stripe orders without introducing superconductivity in La1.875Ba0.125CuO4' (arXiv:2306.07869v1)

Author

Nicoletti, D., Buzzi, M., Först, M., and Cavalleri, A.

Abstract

In the manuscript arXiv:2306.07869v1, N. L. Wang and co-authors report the results of a near-infrared pump / terahertz probe study in the stripe-ordered cuprate La1.875Ba0.125CuO4. They measured a change in optical conductivity, but did not find signatures of transient superconductivity. From this observation they extrapolate that in all cuprates in which striped states have been excited with light, there must be no light-induced superconductivity. They conclude that "transient superconductivity cannot be induced by melting of the competing stripe orders with pump pulses whose photon energy is much higher than the superconducting gap of cuprates." Here we show that this extrapolation is unwarranted. First, the absence of light-induced superconductivity in this particular compound was already reported in a previous paper, which instead showed positive evidence for La1.885Ba0.115CuO4. In addition, the experiment discussed here used photo-excitation with too low fluence and at a suboptimal wavelength. More broadly, a negative result in one compound is rarely compelling indication of the absence of an effect in an entire class of materials.

Abstract

Many functionally relevant ferroic phenomena in quantum materials can be manipulated by driving the lattice coherently with optical and terahertz pulses. New physical phenomena and non-equilibrium phases that have no equilibrium counterpart have been discovered following these protocols. The underlying structural dynamics has been mostly studied by recording the average atomic position along dynamical structural coordinates with elastic scattering methods. However, crystal lattice fluctuations, which are known to influence phase transitions in equilibrium, are also expected to determine these dynamics but have rarely been explored. Here, we study the driven dynamics of the quantum paraelectric SrTiO3, in which mid-infrared drives have been shown to induce a metastable ferroelectric state. Crucial in these physics is the competition between the polar instability and antiferrodistortive rotations, which in equilibrium frustrate the formation of long-range ferroelectricity. We make use of high intensity mid-infrared optical pulses to resonantly drive a Ti-O stretching mode at 17 THz, and we measure the resulting change in lattice fluctuations using time-resolved x-ray diffuse scattering at a free electron laser. After a prompt increase, we observe a long-lived quench in R-point antiferrodistortive lattice fluctuations. The enhancement and reduction in lattice fluctuations are explained theoretically by considering fourth-order nonlinear phononic interactions and third-order coupling to the driven optical phonon and to lattice strain, respectively. These observations provide a number of new and testable hypotheses for the physics of light-induced ferroelectricity.

Abstract

Motivated by recent experiments that observed low-frequency second-order optical responses in doped striped superconductors, here we investigate the nonlinear electrodynamics of systems exhibiting a charge density wave (CDW) order parameter. Due to the Bragg scattering off the CDW order, an incoming spatially homogeneous electric field in addition to zero momentum current generates Umklapp currents that are modulated in space at momenta of the reciprocal CDW lattice. In particular, here we predict and microscopically evaluate the Umklapp shift current, a finite momentum analog of the regular shift current which represents the second-order optical process that downconverts homogeneous AC electric field into low-frequency, zero momentum current. Specifically, we evaluate real-time response functions within mean-field theory via the Keldysh technique and use the Peierls substitution to compute observables at finite momenta in lattice models. We find that systems with certain lattice symmetries (such as inversion symmetry), where the regular shift current is disallowed, may give rise to the Umklapp one. We apply our framework to investigate lattice symmetries in layered materials with helical-like stripes and show that both types of shift currents provide insight into the nature of intertwined phases of matter. Finally, we discuss the relation of our findings to recent experiments in striped superconductors.

Abstract

Resonant optical excitation of certain molecular vibrations in $��$-(BEDT-TTF)$_2$Cu[N(CN)$_2$]Br has been shown to induce transient superconducting-like optical properties at temperatures far above equilibrium $T_c$. Here, we report experiments across the bandwidth-tuned phase diagram of this class of materials, and study the Mott insulator $��$-(BEDT-TTF)$_2$Cu[N(CN)$_2$]Cl and the metallic compound $��$-(BEDT-TTF)$_2$Cu(NCS)$_2$. We find non-equilibrium photoinduced superconductivity only in $��$-(BEDT-TTF)$_2$Cu[N(CN)$_2$]Br, indicating that the proximity to the Mott insulating phase and possibly the presence of preexisting superconducting fluctuations are pre-requisites for this effect., 14 pages, 4 figures

Abstract

Introduction. Vasa vasorum (VV) neovasculogenic potential is now widely accepted, and possibly related to the presence of progenitor cells. We studied the morphology of VV in healthy arteries and their immunohistochemical (IHC) expression of Nestin and WT1, two markers of endothelial progenitor cells. Materials and Methods. Twenty arteries from 16 multiorgan donors were analyzed; IHC was performed manually (CD34, CD31, Nestin) or automatically (WT1). Microvessel positivity “density” for each antibody was calculated dividing vascular adventitia in 1-mm2 fields with an ocular micrometer. Double immunofluorescence was used to investigate Nestin and WT1 co-localization in VV. Results. The mean positivity “densities” for CD31, CD34, Nestin and WT1 were 13.63, 12.20, 8.90 and 7.98/mm2 respectively. Mean Nestin/CD31 and WT1/CD31 ratios were 0.69 and 0.63 respectively. VV

Abstract

The recently discovered magnetization reversal driven solely by a femtosecond laser pulse has been shown to be a promising way to record information at record breaking speeds. Seeking to improve the recording density has raised intriguing fundamental question about the feasibility to combine the ultrafast temporal with sub-wavelength spatial resolution of magnetic recording. Here we report about the first experimental demonstration of sub-diffraction and sub-100 ps all-optical magnetic switching. Using computational methods we reveal the feasibility of sub-diffraction magnetic switching even for an unfocused incoming laser pulse. This effect is achieved via structuring the sample such that the laser pulse experiences a passive wavefront shaping as it couples and propagates inside the magnetic structure. Time-resolved studies with the help of photo-emission electron microscopy clearly reveal that the sub-wavelength switching with the help of the passive wave-front shaping can be pushed into sub-100 ps regime.

Abstract

The possible prognostic value of the position of the breakpoint within the M-BCR in patients with Phl+ CML is still being debated. We analyzed the DNA rearrangements and the transcript types of 244 patients and tried to correlate the data obtained with prognostic features, defined according to Sokal's risk index, and with chronic phase and/or survival duration. The exact location of the breakpoint, either 5' or 3' to the Hind III restriction site within the M-BCR was identified. Moreover, the exact M-BCR subregion was also identified. As a whole, 150 pts were rearranged in the 5' part and 94 in the 3' part of the M-BCR. No correlation was observed between the site of rearrangement on the one hand and the Sokal's prognostic index and survival, on the other. Transcript analysis was performed in 130 patients; 59 carried an a2b2 and 69 an a2b3 pattern. Two patients carried both transcripts. Of the patients rearranged in the 5' area, according to Southern blotting, 29.2% showed an a2b3 transcript. Therefore, R...

Abstract

Today, ICT technology is increasingly applied in a variety of environments, including archaeology, with multiple benefits. Radio-frequency identification (RFID) is a technology for automatic identification of objects, persons and animals using radio waves. It consists of two components: readers and tags. Tags store information that readers are able to retrieve. Tags may be passive, active (powered by battery) or semi-active. Passive tags are especially convenient since they are small, inexpensive and do not pose maintenance problems. Passive tags transmit their unique id by using the energy induced by the reader. This technology was successfully applied in museums to improve user experience and increase the efficiency of the physical inventory. We discuss the potential of using UHF (Ultra High Frequency) RFID passive tags for efficient tracking and rapid identification of items from archaeological sites to museum, highlighting advantages of this approach, as well as its technological limits.

Abstract

The enormous amount of information available today on the Internet requires the use of search tools such as search engines, meta-search engines and directories for rapid retrieval of useful and appropriate information. Indexing a website's content by search engine allows its information to be located quickly and improves the site's usability. In the case of a large number of pages distributed over different systems (e.g. an organization with several autonomous branches/departments) a local search engine rapidly provides a comprehensive overview of all information and services offered. Local indexing generally has fewer requirements than global indexing (i.e. resources, performance, code optimization), thus public-domain SW can be used effectively. In this paper, we compare four open-source search engines available in the Unix environment in order to evaluate their features and effectiveness, and to understand any problems that may arise in an operative environment. Specifically, the comparison includes: o The SW features (installation, configuration options, scalability); o User interfaces; o The overall performance when indexing a sample page set; o Effectiveness of searches; o State of development and maintenance; o Documentation and support.

Abstract

In virtually all Ph1 chromosome-positive CML patients, the breakpoint on chromosome 22 maps in a very restricted area of 5.8 Kb, which has been named "breakpoint cluster region" or "bcr". Several molecular probes of this region are presently available, and this makes the molecular diagnosis of CML a useful approach which can be particularly important in those cases in which cytogenetic analysis does not reveal the presence of a Ph1 chromosome. Here we report the problems and our experience during the molecular analysis of the 478 patients examined so far.Molecular analyses were performed after digestion of the DNA with 2 to 4 restriction enzymes and hybridization with different probes. Individual samples were subjected to PCR since no rearrangements had been obtained with Southern blotting.Rearrangement bands were detected in all the samples examined. In 473 cases the breakpoint was located within the bcr. In one of these cases, it was detected only after PCR analysis, and in two cases only after the use of the PHL/BCR probe. In 5 cases the breakpoint was localized either 5' or 3' with respect to the bcr.In this paper, the criteria for a correct molecular diagnosis of CML are presented. The "PHL/BCR" probe appeared to be very specific and time-saving, since it required only one digestion to evidence the rearrangement. Our results confirm the high specificity of the breakpoint on chromosome 22 in CML and the relatively rare incidence of molecular variants.

Abstract

The role of in vivo administration of lymphoblastoid alpha-interferon (IFN-alpha) on the immune status of 12 patients with hairy cell leukemia (HCL) was studied. In most cases an increase in T3(CD3), T4(CD4), and T8(CD8) lymphocyte subsets was documented at the same time as hairy cells disappeared from the circulation. This led in most cases to an improved T4/T8 ratio. The effect of treatment with IFN-alpha was particularly evident on the natural killer cell compartment, which is often functionally depressed in HCL at diagnosis. After therapy, a progressive increase in the cytotoxic activity was observed in most patients. This was more evident 6-9 months after commencing treatment. These findings suggest that, in addition to the known clinicohematological effects, IFN-alpha can improve both the T and natural killer compartments in patients with HCL.
