This RUI award funds the research activities of Professor Matthew Lippert at SUNY Old Westbury.Over the past two decades, string theory has developed into a powerful tool for attacking challenging problems in a wide range of systems, from electrons in high-temperature superconductors to the ultra-dense cores of neutron stars. The key tool is "duality", a translation between two very different descriptions of the same physical system. As such, dualities enable string theory to rephrase many otherwise intractable problems into the form of questions that can be answered with vastly simpler calculations. As part of his research, Professor Lippert will conduct several research projects which use string theory models to investigate open questions arising in a variety of interdisciplinary contexts. This research advances the national interest of promoting scientific progress by forging broad interdisciplinary connections between string theory, nuclear physics, astrophysics, and condensed matter physics. Such bridges enable the exchange of ideas and techniques between different fields of physics, enriching and advancing them all. Furthermore, this RUI grant will enhance undergraduate physics research at SUNY Old Westbury, an exceptionally diverse, federally recognized minority-serving institution, with large Black and Hispanic populations. Professor Lippert will involve students from severely underrepresented groups in his research, allowing them to acquire valuable experience, to improve their practical quantitative and computing skills, and to gain a hands-on appreciation for how actual science is done. More specifically, this research uses gauge/gravity duality to investigate open questions in strongly coupled quantum field theories, organized around three topics. The physics of strongly interacting fermions and the quantum Hall effect on a spherical defect will be explored using a holographic probe brane model. The topology and the lack of boundary are predicted to result in significantly different behavior compared with a planar system. The poorly understood behavior of cold, dense nuclear matter at the core of neutron stars will be investigated using holographic models of QCD. Realistically and tractably including baryons in holographic models of QCD continues to be a challenge. Far-from-equilibrium dynamics within quantum systems will be studied using holographic methods. Advances in ultra-fast techniques have resulted in unprecedented control of quantum electronic systems, yielding a range of novel phenomena. This research investigates the out-of-equilibrium dynamics of non-equilibrium steady states resulting from periodic driving.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.

这个Rui奖资助了纽约州立大学老西伯里分校Matthew Lippert教授的研究活动。在过去的二十年里，弦理论已经发展成为一个强大的工具，用于解决从高温超导体中的电子到中子星的超高密度核心等广泛系统中的挑战性问题。关键的工具是“二元性”，即对同一物理系统的两种截然不同的描述之间的翻译。因此，对偶性使弦理论能够将许多原本难以解决的问题重新表述为问题的形式，这些问题可以用简单得多的计算来回答。作为他研究的一部分，利伯特教授将进行几个研究项目，这些项目使用弦理论模型来调查在各种跨学科背景下出现的公开问题。这项研究通过在弦理论、核物理、天体物理和凝聚态物理之间建立广泛的跨学科联系，促进了促进科学进步的国家利益。这样的桥梁使不同物理领域之间的思想和技术得以交流，丰富和促进了所有这些领域。此外，这笔Rui助学金将加强纽约州立大学老韦斯特伯里分校的本科生物理研究，这是一所特别多样化的、得到联邦政府承认的少数族裔服务机构，拥有大量黑人和西班牙裔人口。利伯特教授将让来自严重缺乏代表性的群体的学生参与他的研究，让他们获得宝贵的经验，提高他们的实际量化和计算技能，并获得对实际科学是如何完成的亲身体验。更具体地说，这项研究使用规范/重力对偶性来研究强耦合量子场论中的公开问题，围绕三个主题组织。利用全息探测膜模型，研究了强相互作用费米子的物理性质和球形缺陷上的量子霍尔效应。预测了这种拓扑结构和边界的缺失将导致与平面系统相比有显著不同的行为。我们将使用QCD的全息模型来研究中子星核心中冷密核物质鲜为人知的行为。现实而又容易理解的是，在QCD的全息模型中包含重子仍然是一个挑战。我们将使用全息方法研究量子系统中远离平衡的动力学。超快技术的进步导致了对量子电子系统的前所未有的控制，产生了一系列新的现象。这项研究调查了周期性驾驶导致的非平衡稳态的不平衡动力学。这一奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
