Radion clouds around evaporating black holes

从蒸发黑洞周围的标量云到玻色子星

From scalar clouds around evaporating black holes to boson star

研究发现，当黑洞绝热蒸发至质量小于云质量一半时，标量云可能形成自引力的玻色子星，揭示了玻色子星形成的新机制及暗物质探测潜力的增强

Smooth and sharp creation of a pointlike source for a $(3+1)$-dimensional quantum field

We analyse the smooth and sharp creation of a pointlike source for a quantised massless scalar field in $(3+1)$-dimensional Minkowski spacetime, as a model for the breakdown of correlations that has been proposed to occur at the horizon of an evaporating black hole. The creation is implemented by a time-dependent self-adjointness parameter at the excised spatial origin. In a smooth creation, the renormalised energy density $\langle T_{00} \rangle$ is well defined away from the source, but it is unbounded both above and below: the outgoing pulse contains an infinite negative energy, while a clo…

带电黑洞在1/N展开中的研究

Charged black holes in the 1/N expansion

研究发现，在大N极限下，带电黑洞通过发射重子失去电荷，最终达到极性并停止演化，为原始黑洞暗物质提供了新的参数空间。
