两维整体单极黑洞时空中的Casimir效应

 两维整体单极黑洞事件视界附近的一个薄层作为Casimir型系统,得到了在Boulware真空、Hartle-Hawking真空和Unruh真空的能动张量.这些值都是在满足Dirichlet边界条件的无质量标量场中得到.应用Wald公理得到了用通常的正规化方法得到的结果.同时,计算了在渐进平直时空下的能量、能量密度和作用在Dirichlet边界上的压强,并由能量得到了Casimir力.

The Casimir effect in two dimensional black hole spacetime with a global monopole

A thin layer of the event horizon vicinity under the two-dimension black hole spacetime with a global monopole is considered as a system of the Casimir type.The energy-momentum tensor is derived in Boulware vacuum,Hartle-Hawking vacuum and Unruh vacuum respectively.The values are derived in the massless scalar field which satisfies the Dirichlet boundary conditions.By the Wald's axioms,the result is the same with one by the usual regularized methods.Meanwhile,energy,energy density,and pressure acting on Dirichlet walls at the asymptotically flat background are also calculated.According to the energy,the Casimir force is derived.
