标题： Geometric phase for an accelerated two-level atom and the Unruh effect

摘要： 我们在开放量子系统的框架下研究了一个均匀加速的两能级原子由于与涨落的真空电磁场浴以多极耦合的方式相互作用而经历非幺正演化时所获得的几何相位。 我们发现，由加速度引起的相位变化原则上可以通过加速原子和惯性原子之间的原子干涉仪观测到，从而为Unruh效应提供证据。 显示英文摘要

摘要： We study, in the framework of open quantum systems, the geometric phase acquired by a uniformly accelerated two-level atom undergoing nonunitary evolution due to its coupling to a bath of fluctuating vacuum electromagnetic fields in the multipolar scheme. We find that the phase variation due to the acceleration can be in principle observed via atomic interferometry between the accelerated atom and the inertial one, thus providing an evidence of the Unruh effect.
