RUI: Holographic Stars and Stripes

该RUI奖资助布鲁克林长岛大学Matthew Lippert教授的研究活动。近年来，弦理论作为一种强大的工具出现，不仅用于理解量子引力和极高能量物理，而且用于研究各种长度尺度的强相互作用系统，从奇异超导体中的电子到中子星的超密核心。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、核物理、天体物理和凝聚态物理之间的跨学科联系。这样的桥梁使不同物理领域之间的思想和技术交流成为可能，丰富和推进了所有这些领域。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。这项拨款还将支持非裔美国人和西班牙裔学生的研究，从而增加STEM领域学生的多样性，从而使这些学生提高他们的实际定量和计算技能，获得对实际科学如何完成的动手欣赏，并瞥见人类知识的令人兴奋的前沿。更具体地说，本研究使用全息规范/重力对偶性来研究强耦合量子场理论中的开放问题，围绕四个主题组织。首先，我们将利用量子cd的全息模型来研究中子星核心冷、致密核物质的行为，以检验最近和正在进行的双中子星合并观测的预测。其次，将使用全息模型研究强耦合条纹态，如电荷密度波，包括它们对外加电磁场的响应以及自发和显式空间对称破缺之间的相互作用。第三，任意子，其不寻常的行为即使在弱耦合下也很难理解，将在强耦合下使用全息对偶描述进行分析。最后，利用全息二象性，本研究将探索某些强相互作用系统松弛到自发对称性破缺的基态的非平衡动力学。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。

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.
