Effects of Quantum Fields on Black Holes

安德森教授将负责一项新的理论引力物理研究项目。他将阐述与黑洞研究有关的三个重要问题。这些问题是：黑洞蒸发过程的终点是什么？关于黑洞是如何形成的信息发生了什么变化？量子场如何改变黑洞的热力学性质？这些研究将围绕量子场改变黑洞内外的时空几何结构的方式展开。这些变化会影响黑洞的热力学性质。它们对黑洞蒸发后留下的东西也有很大的影响。关于黑洞如何形成的信息会发生什么，可能既取决于其视界内的时空几何，也取决于黑洞蒸发后留下的东西。另一个被提出的研究是发展了一种在自由量子化光场的模方程不是完全可分的情况下进行量子场论计算的实用方法。这些结果应该会显著增强我们研究过程细节的能力，例如黑洞蒸发、粒子产生引起的强电场的衰变，以及核物理中重离子碰撞产生的粒子。

A new research program in theoretical gravitational physics will be undertaken by Prof. Anderson. He will address three important issues relating to the study of black holes. These are the questions: What is the end point of the black hole evaporation process? What happens to the information about how a black hole formed? How do quantum fields alter the thermodynamic properties of a black hole? The investigations will center around the ways in which quantum fields alter the spacetime geometry both inside and outside of a black hole. These alterations affect the thermodynamic properties of the black hole. They also have a strong influence on what is left after the black hole finishes evaporating. What happens to the information about how a black hole formed may depend on both the spacetime geometry inside its event horizon and what is left after the black hole finishes evaporating. Another proposed investigation is the development of a practical way to make computations in quantum field theory when the mode equation for free quantized fields is not completely separable. The results should significantly enhance our ability to study the details of processes such as black hole evaporation, the decay of a strong electric field due to particle production, and particle production due to heavy ion collisions in nuclear physics.
