Quantum Fields and Black Holes

* * * 9734834 hiscockdr。Hiscock的研究小组将继续研究对黑洞几何形状的半经典效应，特别强调在半经典引力下是否可能存在零度黑洞“残余物”（代表黑洞蒸发的可能终点），以及对黑洞内部因果结构的半经典效应。虽然人们普遍认为，半经典引力至多是一些尚未明确定义的完整量子引力理论的近似值，但它仍然是目前研究强引力场（如黑洞周围和大爆炸附近）中量子效应的最佳工具。目前的工作将扩展我们对这些体系中半经典效应的认识，并作为量子引力基本理论计算的检验

***9734834HiscockDr. Hiscock's research group will continue their work on semiclassical effects on black hole geometries, with particular emphasis on whether zero-temperature black hole "remnants" (representing possible endpoints of black hole evaporation) are possible within semiclassical gravity, and on semiclassical effects on the causal structure of black hole interiors.While it is widely accepted that semiclassical gravity is at best an approximation to some as yet ill-defined full theory of quantum gravity, it is nevertheless the best present tool available for the study of quantum effects in strong gravitational fields, such as around black holes and near the Big Bang. The present work will extend our knowledge of semiclassical effects in these regimes, and act as checks for calculations in proposed fundamental theories of quantum gravity.***
