论文摘要
这是对有关电场和压力张量操作员及其物理影响的量子波动的最新工作的评论。电场真空波动的概率分布是高斯,但是对于二次操作员(例如能量密度)的概率分布可能会更慢地减小尾巴,从而增加大波动的概率。这种效果对如何执行测量的细节非常敏感。将讨论这些大波动的一些可能的物理影响。
This is a review of recent work on quantum fluctuations of the electric field and of stress tensor operators and their physical effects. The probability distribution for vacuum fluctuations of the electric field is Gaussian, but that for quadratic operators, such as the energy density, can have a more slowly decreasing tail, leading to an enhanced probability of large fluctuations. This effect is very sensitive to the details of how the measurement is performed. Some possible physical effects of these large fluctuations will be discussed.
