Quantum Field and Gravitational Waves in Black Holes and the Early Universe

该奖项支持旨在理解黑洞演化后期量子场过程后果的研究，并探索引力如何与原子光学和介观系统中的量子测量接口。其目的是确定由于量子场导致的黑洞视界附近的度量波动的幅度，以及霍金辐射如何在准平衡（盒子中）和非平衡（蒸发）条件下对黑洞的状态和动力学产生反作用和影响。这项研究是必不可少的，以评估的有效性索赔的基础上半经典引力，有关黑洞的最终状态和信息损失的问题。量子系统中引力效应的研究探索了广义相对论和量子力学的交叉点，而不是像量子引力中通常所做的那样急于强迫它们的结合-引力如何与原子光学和介观系统相互作用并影响量子测量，量子和随机力如何引入对测地线的修正，以及引力场是否在退散量子系统中发挥特殊作用。这项研究借鉴了许多物理学领域的技术和见解，并反过来为这些领域做出贡献。

This award supports research aimed at understanding the consequences of quantum field processes at the late stage evolution of black holes and exploring how gravity interfaces with quantum measurements in atomic-optical and mesoscopic systems. The aim is to determine the magnitude of metric fluctuations near the black hole horizon due to quantum fields, and how Hawking radiation back-reacts on and affects the state and dynamics of a black hole, under quasi-equilibrium (in a box) and non-equilibrium (evaporating) conditions. This study is essential to assess the validity of claims based on semiclassical gravity, pertaining to the black hole end-state and information loss issues. Study of gravitational effects in quantum systems explores the intersection of general relativity and quantum mechanics, rather than hasten to force their union, as is customarily done in quantum gravity---how gravity interacts with atomic-optical and mesoscopic systems and affects quantum measurements and how quantum and stochastic forces introduce corrections to geodesics, and whether gravitational fields play a special role in decohering quantum systems. This investigation draws on techniques and insights from a number of fields of physics, and in turn contributes to these fields.
