论文摘要
对INRUH效应的研究自然引起了人们对温度与加速度之间的类比的更深入理解的兴趣。一个反复出现的问题是,在纯热力学实验中,是否可以将加速框架与惯性热浴区分开,文献中已经解决了此类问题,并且尚未完全达成共识。在目前的工作中,我们使用开放量子系统形式主义来研究存在加速度和背景温度的情况。我们发现从马尔可维亚的进化中,与外部标量场的热状态相互作用的渐近状态密度和纠缠产生。我们的结果表明,对异常和背景温度的影响有很小的不对称性。解决非零背景温度案例既具有理论和现象学的兴趣,因此作者希望丰富有关该主题的现有讨论。
The study of the Unruh effect naturally raises the interest for a deeper understanding of the analogy between temperature and acceleration. A recurring question is whether an accelerated frame can be distinguished from an inertial thermal bath in pure thermodynamic experiments, such problem has been approached in the literature and a consensus is yet to be fully reached. In the present work we use the open quantum system formalism to investigate the case where both acceleration and background temperature are present. We find the asymptotic state density and entanglement generation from the Markovian evolution of accelerated qubits interacting with a thermal state of the external scalar field. Our results suggest that there is a very small asymmetry on the effects of the Unruh and background temperatures. Addressing the nonzero background temperature case is of both theoretical and phenomenological interest, thus the authors hope to enrich the existing discussions on the topic.
