Effects of Quantized Fields on Black Hole and Cosmological Spacetimes

安德森教授将从事几个研究量子效应的项目，因为它们与黑洞和宇宙学有关。 对于黑洞，他将研究量子场如何改变黑洞的温度和熵，以及在黑洞蒸发过程结束时会发生什么。 在宇宙学中，他将研究量子效应是否会导致一个非常迅速膨胀的宇宙变得不稳定，并以不同的方式膨胀，以及研究宇宙在其历史早期经历了一段称为暴胀的极其迅速的膨胀时期后的粒子产生。通过研究量子场如何影响黑洞的细节，人们可以解决诸如黑洞之后留下什么之类的问题。空穴完成蒸发，是否需要任何新的物理学来描述蒸发过程。 通过研究早期宇宙中的粒子产生，人们可以确切地研究宇宙中的物质和辐射是如何产生的。

Prof. Anderson is going to work on several projects studying quantum effects as they relate to both black holes and cosmology. For black holes he will study the question of how quantum fields alter the temperatures and entropies of black holes, as well as what happens at the end ofthe black hole evaporation process. In cosmology he will investigate whether quantum effects can cause a very rapidly expanding universe to become unstable and expand in a different way than it otherwise would, as well as study particle production in the universe after it underwent an extremely rapid period of expansion called inflation early in its history.By studying the details of how quantum fields affect black holes one can address such questions as what is left after a black hole finishes evaporating and is there any new physics that is required to describe the evaporation process. By studying particle production in the early universe one can investigate exactly how the matter and radiation in the universe were created.
