This award funds the research activities of Professors Igor Klebanov, Simone Giombi, and Herman Verlinde at Princeton University.The unification of Quantum Mechanics and Special Relativity has produced the powerful apparatus of Quantum Field Theory. It has applications in a variety of fields of physics, ranging from elementary particles to critical phenomena. A much more difficult problem is Quantum Gravity, the unification of Quantum Mechanics with General Relativity, which is important for addressing the mysteries of black-hole physics. Remarkably, there are precise relations between Quantum Gravity and Quantum Field Theory, and deepening our fundamental understanding of these theories is one of the key goals of this research. Another goal is the application of these theories to specific models and exploration of their connections with Quantum Information theory. This research is therefore in the national interest in that it helps to advance fundamental scientific progress in the United States. Postdocs and students will be very important for carrying out this research program; educating and mentoring such students thus constitutes its key broader impact.At a more technical level, the research will aim to shed new light on the conformal field theories in various spacetime dimensions. This includes non-unitary models which sometimes have simple formulations in statistical mechanics. Via the Anti-de Sitter/Conformal Field Theory duality, the models with a large number of degrees of freedom can teach us more about the quantum theory of gravity, including the higher-spin fields. The project also includes the exploration of Quantum Field Theories in the presence of boundaries and defects, such as the study of Wilson loops in gauge theory and of theories with boundary interactions. The research on Quantum Gravity in model black-hole, wormhole and cosmological spacetimes will aim to address some of the deep mysteries in fundamental physics. This research also offers prospects of cross-fertilization with condensed-matter physics and Quantum Information theory through the exploration of lattice Hamiltonians for interacting qubits. Of particular interest are the quantum many-body scar states that can avoid thermalization and decoherence; in some models they can be constructed using the methods of Group Theory.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.

该奖项为普林斯顿大学的伊戈尔·克莱巴诺夫（Igor Klebanov），西蒙妮·乔邦（Simone Giombi）和赫尔曼·维林德（Herman Verlinde）教授的研究活动提供了资金。量子力学和特殊相对论的统一产生了量子场理论的强大设备。 它在各种物理领域具有应用，从基本颗粒到关键现象。 一个更困难的问题是量子重力，量子力学与一般相对论的统一，这对于解决黑洞物理的奥秘很重要。值得注意的是，量子重力与量子场理论之间存在精确的关系，加深我们对这些理论的基本理解是这项研究的关键目标之一。 另一个目标是将这些理论应用于特定模型，并使用量子信息理论探索它们的联系。 因此，这项研究符合国家利益，因为它有助于促进美国的基本科学进步。 博士后和学生对于执行该研究计划非常重要； 因此，对这些学生进行教育和指导构成了更广泛的影响。在更具技术性的水平上，该研究将旨在在各个时空维度中对保形场理论进行新的启示。这包括有时在统计力学中具有简单配方的非单身模型。通过抗DE保姆/保形场理论二重性，具有大量自由度的模型可以教会我们更多有关重力量子理论的信息，包括高旋转场。该项目还包括在存在边界和缺陷的情况下对量子场理论的探索，例如仪表理论中威尔逊环的研究以及与边界相互作用的理论。模型黑洞，虫洞和宇宙学的量子重力的研究将旨在解决基本物理学中的一些深度谜团。这项研究还通过探索晶格汉密尔顿人进行相互作用的量子，并提供了与凝结物理学和量子信息理论的交叉施用前景。特别令人感兴趣的是量子多体疤痕状态，可以避免热化和脱糖。 在某些模型中，可以使用小组理论的方法来构建它们。该奖项反映了NSF的法定使命，并被认为是值得通过基金会的知识分子优点和更广泛影响的评论标准来评估的。
