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

该奖项支持旨在了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相结合。其目的是确定由量子场引起的黑洞视界附近的度规波动的大小，以及在准平衡(在盒子中)和非平衡(蒸发)条件下，霍金辐射如何对黑洞的状态和动力学产生反向反应和影响。这项研究对于评估基于半经典引力的关于黑洞终态和信息丢失问题的主张的有效性是至关重要的。对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，而不是像量子重力中通常所做的那样，急于迫使它们结合-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，量子和随机力如何对测地线引入修正，以及引力场是否在拆分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了贡献。

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.
