In this work, we show that a universal quantum work relation for a quantum system driven arbitrarily far from equilibrium extends to a parity-time- (PT-) symmetric quantum system with unbroken PT symmetry, which is a consequence of microscopic reversibility. The quantum Jarzynski equality, linear response theory, and Onsager reciprocal relations for the PT-symmetric quantum system are recovered as special cases of the universal quantum work relation in a PT-symmetric quantum system. In the regime of broken PT symmetry, the universal quantum work relation does not hold because the norm is not preserved during the dynamics.
在这项工作中，我们表明，对于一个被任意远地驱动远离平衡的量子系统，一个通用的量子功关系扩展到一个具有不破缺的宇称时间（PT）对称的量子系统，这是微观可逆性的结果。量子 Jarzynski 等式、线性响应理论和 PT 对称量子系统的 Onsager 互易关系都是 PT 对称量子系统中通用量子功关系的特例。在破缺的 PT 对称的情况下，通用量子功关系不成立，因为在动力学过程中范数不守恒。
