我们能检测到高强度激光中的“Unruh辐射”吗?

Can we detect "Unruh radiation" in the high intensity lasers?

Satoshi Iso, Yasuhiro Yamamoto, Sen Zhang

摘要:

加速粒子将闵可夫斯基真空视为热激发,这被称为Unruh效应。由于与热浴的相互作用,颗粒像热浴中的布朗运动一样随机移动。已经讨论过,加速的带电粒子除了拉莫尔辐射之外还可能发射额外的辐射(Unruh辐射),并且正在计划通过使用高强度激光来检测这种辐射的实验。然而,有相反的论点,辐射被真空波动和波动运动的辐射之间的干涉效应所抵消。在本报告中,我们回顾了我们最近对Unruh辐射问题的分析。在这篇报告中,我们特别考虑了标量QED中加速粒子的热化,并推导了热化的弛豫时间。

英文摘要:

An accelerated particle sees the Minkowski vacuum as thermally excited, which is called the Unruh effect. Due to an interaction with the thermal bath, the particle moves stochastically like the Brownian motion in a heat bath. It has been discussed that the accelerated charged particle may emit extra radiation (the Unruh radiation) besides the Larmor radiation, and experiments are under planning to detect such radiation by using ultrahigh intensity lasers. There are, however, counterarguments that the radiation is canceled by an interference effect between the vacuum fluctuation and the radiation from the fluctuating motion. In this reports, we review our recent analysis on the issue of the Unruh radiation. In this report, we particularly consider the thermalization of an accelerated particle in the scalar QED, and derive the relaxation time of the thermalization.
