半整体双曲时空上的量子场

Quantum fields on semi-globally hyperbolic space-times

Daan Willem Janssen

摘要:

我们介绍了一类时空模型奇异事件,如蒸发黑洞和拓扑结构的变化,我们称之为半全球双曲时空。在这些时空中,我们的目标是研究合理的量子场论的存在。我们在这些时空上建立了线性标量量子场论的概念,展示了这样一个理论是如何构建的,并在这些理论上引入了全局动力学的概念。将这些构造应用于黑洞蒸发和拓扑变化的时空,我们发现代数的存在性可以相对容易地建立,而这些代数上合理态的存在性仍然是一个未解决的问题.

英文摘要:

We introduce a class of space-times modeling singular events such as evaporating black holes and topology changes, which we dub as semi-globally hyperbolic space-times. On these space-times we aim to study the existence of reasonable quantum field theories. We establish a notion of linear scalar quantum field theories on these space-times, show how such a theory might be constructed and introduce notions of global dynamics on these theories. Applying these constructions to both black hole evaporation and topology changing space-times, we find that existence of algebras can be relatively easily established, while the existence of reasonable states on these algebras remains an unsolved problem.
