静态黑弦背景下的大质量标量场的量子化

Quantization of massive scalar fields over static black string backgrounds

Owen Pavel Fernandez Piedra, Alejandro Cabo Montes de Oca

摘要:

本文利用Schwinger-DeWitt近似解析地计算了耦合到任意柱对称引力场位形的大质量标量场的能量动量张量相应分量的重整化平均值,直到质量倒数的二阶.一般的结果,明确推导出紧凑的解析表达式的能量动量张量在特定的背景下的黑弦时空。在黑弦的情况下,在这项工作中考虑,我们证明,违反弱能量条件发生在视界的时空值的耦合常数,其中包括作为特殊情况下最有趣的最小和共形耦合。

英文摘要:

The renormalized mean value of the corresponding components of the Energy-Momentum tensor for massive scalar fields coupled to an arbitrary gravitational field configuration having cylindrical symmetry are analytically evaluated using the Schwinger-DeWitt approximation, up to second order in the inverse mass value. The general results are employed to explicitly derive compact analytical expressions for the Energy-Momentum tensor in the particular background of the Black-String spacetime. In the case of the Black String considered in this work, we proof that a violation of the weak energy condition occur at the horizon of the space-time for values of the coupling constant, that include as particular cases the most interesting of minimal and conformal coupling.
