摘要

研究了环向紧化的伦德勒时空中带电标量场的场平方期望值。比较了Fulling-Rindler真空和Minkowski真空的期望值。对于场算子沿紧维的周期性条件下的一般相位，给出了这些期望值之差的积分表示。磁场平方的真空期望值是紧化尺寸包围的磁通量的一个偶周期函数。给出了在伦德勒视界附近和小加速度下的简单渐近表达式。我们证明了Fulling-Rindler真空的平均场平方小于Minkowski真空的期望值。

Polarization of the Fulling-Rindler Vacuum in Models with Compact Dimensions

We investigate the expectation value of the field squared for a charged scalar field in the Rindler spacetime with toroidally compact dimensions. The expectation values are compared for the Fulling-Rindler and Minkowski vacua. For general phases in the periodicity conditions on the field operator along compact dimensions, integral representations are provided for the difference of those expectation values. The vacuum expectation value of the field squared is an even periodic function of the magnetic flux enclosed by compact dimensions. Simple asymptotic expressions are given near the Rindler horizon and for small accelerations. We show that the mean field squared in the Fulling-Rindler vacuum is smaller than the respective expectation value for the Minkowski vacuum.
