静态黑弦背景中大质量旋量场的真空极化

Vacuum polarization of massive spinor fields in 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组态的大质量旋量场的量子拉格朗日量和相应的能量动量张量分量的重整化平均值,直到质量倒数的二阶.利用这些一般性结果,在黑弦时空的特殊背景下,得到了量子平均拉氏量和能量动量张量的紧致解析表达式。

英文摘要:

The renormalized mean value of the quantum Lagrangian and the corresponding components of the Energy-Momentum tensor for massive spinor 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 quantum mean Lagrangian and Energy- Momentum tensor in the particular background of the Black-String space-time.
