霍金辐射、协变边界条件与真空态

Hawking Radiation, Covariant Boundary Conditions and Vacuum States

Rabin Banerjee, Shailesh Kulkarni

摘要:

由手征有效作用量得到了协变手征流$<J_μ>$和协变手征能量动量张量$<T_{μν}>$的基本特征.这些结果被用来证明最近的方法\cite{Isowilczek,Isoumtwilczek,shailesh,shailesh2,Banerjee}的手征规范和引力异常计算霍金通量的协变边界条件。我们还讨论了我们的结果与传统的计算在不同的(Unruh,Hartle-Hawking和Boulware)状态的非手征电流和应力张量的连接。

英文摘要:

The basic characteristics of the covariant chiral current $<J_μ>$ and the covariant chiral energy-momentum tensor $<T_{μν}>$ are obtained from a chiral effective action. These results are used to justify the covariant boundary condition used in recent approaches \cite{Isowilczek,Isoumtwilczek,shailesh,shailesh2,Banerjee} of computing the Hawking flux from chiral gauge and gravitational anomalies. We also discuss a connection of our results with the conventional calculation of nonchiral currents and stress tensors in different (Unruh, Hartle-Hawking and Boulware) states.
