Postdoctoral Fellowship: MPS-Ascend: Vortex-beam Spectroscopy of Type-II Superconductors in the THz Regime

vladimir Martinez被授予美国国家科学基金会数学与物理科学提升博士后研究奖学金（NSF MPS-Ascend）。该奖学金的主办机构是新泽西理工学院，赞助科学家是物理系的Andrei Sirenko博士。这个项目的目标是波长约为1毫米的红外光与高温超导体之间的相互作用。高温超导体可以不耗散地排出磁场并传导电流，当受到一定强度的磁场作用时，会形成磁漩涡。这种特殊条件的光，也被称为涡旋光束，其轮廓与超导体中的这些漩涡相似。这种组合允许研究和控制它们增强的相互作用。这项研究提供的见解可能会导致超导体技术的突破，如磁悬浮列车、粒子加速器和超导量子干涉装置（squid）。此外，该项目旨在通过与主办机构合作，从当地高中招募学生参加一系列使用超导体和其他量子实验的互动演示，以扩大STEM和量子科学领域代表性不足的群体的参与。技术摘要：本项目利用低温高磁场下相干同步辐射涡旋光束在太赫兹和红外光谱范围内研究ii型超导体。涡旋光束具有甜甜圈形状的强度分布和波前的螺旋结构，类似于超导涡流，超导环围绕着正常的金属芯。该项目将深入研究超导涡旋的发展、涡旋状态的电动力学及其与涡旋光的拓扑增强相互作用。PI还将为新泽西理工学院和乒乓球高中（K-12）之间的持续合作做出贡献，通过演示和实验提高高中生对量子科学的兴趣和参与。量子计算、密码学和材料等相互关联领域的进展取决于新一代科学家和工程师对这些新需求和挑战感兴趣并准备好迎接这些新挑战。首席研究员将展示使用超导体和涡旋光束的互动演示，以及声学和非线性量子光学的其他实验，并将通过招募包括他的家乡新泽西州伊丽莎白在内的周边高中系统的学生来增加BIPOC（黑人土著和有色人种）对活动的参与。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Non-technical AbstractVladimir Martinez is awarded an NSF Mathematical and Physical Sciences Ascending Postdoctoral Research Fellowship (NSF MPS-Ascend). The host institution for the fellowship is New Jersey Institute of Technology, and the sponsoring scientist is Dr. Andrei Sirenko from the physics department. This project targets the interaction between infrared light with wavelengths of about 1 mm and high-temperature superconductors. High-temperature superconductors, which are known to expel magnetic field and conduct currents without dissipation, form magnetic whirlpools when subject to magnetic fields of a certain strength. The specially conditioned light, also known as vortex beams, has a profile similar to these whirlpools in superconductors. This combination allows the study and control of their enhanced interaction. The insight provided by this study can lead to breakthroughs in superconductor-based technologies like maglev trains, particle accelerators and superconducting quantum interference devices (SQUIDs). Additionally, the project aims at broadening participation amongst underrepresented groups in STEM and quantum sciences by collaborating with the host institution to recruit students from local high schools to join in a series of interactive demonstrations using superconductors and other quantum experiments.Technical Abstract:This project investigates type-II superconductors using vortex beams of coherent synchrotron radiation in the THz and infrared spectral ranges at low temperatures and high magnetic fields. Vortex beams have a doughnut-shaped intensity distribution and spiral structure of the wave fronts, which are analogous to superconducting vortices, with superconducting rings surrounding normal metal cores. The project will yield insight into the development of superconducting vortices and the electrodynamics of the vortex state and its topologically-enhanced interactions with vortex light. The PI will also contribute to an ongoing collaboration between the New Jersey Institute of Technology and the Pingry high school (K-12) to increase interest and participation among high school students in quantum sciences through demos and experiments Progress in the interconnected fields of quantum computing, cryptography, and materials hinges on a new generation of scientists and engineers interested and ready to meet these new demands and challenges. The principal investigator will present interactive demonstrations using superconductors and vortex beams and other experiments in acoustic and nonlinear quantum optics and will increase BIPOC (Black Indigenous and People of Color) participation in the activities by recruiting students from the surrounding high school systems including his hometown of Elizabeth, NJ.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
