Abstract

The recently discovered spin-active boron vacancy (V$_\text{B}^-$) defect center in hexagonal boron nitride (hBN) has high contrast optically-detected magnetic resonance (ODMR) at room-temperature, with a spin-triplet ground-state that shows promise as a quantum sensor. Here we report temperature-dependent ODMR spectroscopy to probe spin within the orbital excited-state. Our experiments determine the excited-state spin Hamiltonian, including a room-temperature zero-field splitting of 2.1 GHz and a g-factor similar to that of the ground-state. We confirm that the resonance is associated with spin rotation in the excited-state using pulsed ODMR measurements, and we observe Zeeman-mediated level anti-crossings in both the orbital ground- and excited-state. Our observation of a single set of excited-state spin-triplet resonance from 10 to 300 K is consistent with an orbital-singlet, which has consequences for understanding the symmetry of this defect. Additionally, the excited-state ODMR has strong temperature dependence of both contrast and transverse anisotropy splitting, enabling promising avenues for quantum sensing., Comment: 13 pages with 5 figures and a supplement

Abstract

The purpose of this study was to evaluate how participating in the Habitat for Humanity house-building process influenced participants’ purpose well-being, social well-being, community well-being, physical and mental well-being, and financial well-being, and how effective Habitat for Humanity is in aiding neighborhood revitalization within the Greater Lafayette area. The research project resulted in a presentation of quantitative data and a testimonial video that highlighted the stories of families that had worked with Habitat for Humanity. Quantitative data was gathered through a survey that addressed respondents’ levels of satisfaction within the various categories of well-being mentioned above. Testimonial information was gathered from interviews with respondents to gain a more personal insight into their stories. The majority of respondents indicated their satisfaction with the overall Habitat for Humanity process and noticeable positive impacts on all aspects of their well-being. Responses were more varied to questions regarding a sense of community within their neighborhoods and a sense of safety. Respondents also indicated occasional dissatisfaction with the inadequate level of homeowner-related education provided through the Habitat for Humanity house-building process. Habitat for Humanity might consider focusing more attention on neighborhood revitalization initiatives including a focus on a general sense of community, overall safety, and periodic check-ins with those who have previously participated in the house-building project.

Abstract

In today’s world, where Digital Communication is becoming an integral part of everyone’s life, cyber security has become a challenge. There are various threats to the data being sent digitally. Changing the data into an unidentifiable form can protect it from attackers. Cryptography is about constructing protocols to prevent third party interventions. Various cryptographic techniques have been proposed to make the data transfer secure. Symmetric key algorithms are the widely used for encryption. The message to be transferred should be as small as possible so as to reduce space complexity that is why compression techniques find their applications in encryption. In this paper, a new approach to encrypt text files using a mix of Huffman coding, combination of symmetric key and public key cryptography and the binary operator XOR is proposed.
