This RUI award funds the research activities of Professor Matthew Lippert at Long Island University Brooklyn.String theory has emerged in recent years as a powerful tool, not just for understanding quantum gravity and extremely high-energy physics, but also for studying a wide range of strongly interacting systems exhibiting a variety of length scales, from electrons in exotic superconductors to the ultra-dense cores of neutron stars. Professor Lippert will conduct research into these systems with the goal of developing interdisciplinary connections between string theory and gravitational physics, 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. As such, this research advances the national interest by fostering the development of basic science within the United States. This grant will also support the research of African-American and Hispanic students, thereby increasing the diversity of students in STEM fields and thereby allowing these students to improve their practical quantitative and computing skills, to gain a hands-on appreciation for how actual science is done, and to glimpse the exciting frontier of human knowledge. More specifically, this research uses holographic gauge/gravity duality to investigate open questions in strongly coupled quantum field theories, organized around four topics. First, the poorly understood behavior of cold, dense nuclear matter at the core of neutron stars will be investigated using holographic models of QCD in order to test predictions against the recent and ongoing observations of binary neutron star mergers. Second, strongly coupled striped states, such as charge density waves, will be studied using holographic models, including their response to applied electromagnetic fields and the interplay between spontaneous and explicit spatial symmetry breaking. Third, anyons, whose unusual behavior is poorly understood even at weak coupling, will be analyzed at strong coupling using a holographic dual description. Finally, using holographic duality, this research will explore the out-of-equilibrium dynamics by which certain strongly interacting systems relax to ground states with spontaneously broken symmetry.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.

RUI奖是对布鲁克林长岛大学Matthew Lippert教授的研究活动的资助。弦理论近年来不仅成为理解量子引力和极高能物理的有力工具，而且也成为研究从奇异超导体中的电子到中子星的超致密核的各种长度尺度的强相互作用系统的有力工具。Lippert教授将对这些系统进行研究，目标是发展弦理论与引力物理学，核物理学，天体物理学和凝聚态物理学之间的跨学科联系。这些桥梁使物理学不同领域之间的思想和技术交流成为可能，丰富和推进了它们。 因此，这项研究通过促进美国基础科学的发展来促进国家利益。 这笔赠款还将支持非裔美国人和西班牙裔学生的研究，从而增加学生在干领域的多样性，从而使这些学生提高他们的实用定量和计算技能，获得实际的欣赏如何科学是做，并瞥见人类知识的令人兴奋的前沿。 更具体地说，这项研究使用全息规范/引力对偶性来研究强耦合量子场论中的开放问题，围绕四个主题组织。 首先，我们将利用量子色动力学的全息模型来研究中子星核心的冷而致密的核物质的行为，以检验对最近和正在进行的双中子星星合并观测的预测。 第二，强耦合条纹状态，如电荷密度波，将使用全息模型，包括它们对施加的电磁场的响应和自发和显式空间对称性破缺之间的相互作用进行研究。 第三，任意子，其不寻常的行为是知之甚少，即使在弱耦合，将分析在强耦合使用全息对偶描述。 最后，利用全息对偶性，本研究将探索某些强相互作用系统弛豫到对称性自发破缺的基态的非平衡动力学。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
