摘要:

我们分析了正性条件对Schwarzschild时空的静态球对称形变的影响。该度规至少在渐近意义上满足存在非平凡应力-能量张量的Einstein方程,我们对该张量施加了多种物理性条件。我们系统研究并比较了这些条件对时空形变的影响。我们结论的普适性适用于带与不带事件视界的经典和量子度规形变。我们进一步讨论了用物理场实现渐近应力-能量张量的最小实现。最后,我们通过讨论量子黑洞的具体模型来阐明结果。

英文摘要:

We analyse the impact of positivity conditions on static spherically symmetric deformations of the Schwarzschild space-time. The metric is taken to satisfy, at least asymptotically, the Einstein equation in the presence of a non-trivial stress-energy tensor, on which we impose various physicality conditions. We systematically study and compare the impact of these conditions on the space-time deformations. The universal nature of our findings applies to both classical and quantum metric deformations with and without event horizons. We further discuss minimal realisations of the asymptotic stress energy tensor in terms of physical fields. Finally, we illustrate our results by discussing concrete models of quantum black holes.
