Abstract

In a recent paper, Deffner and Saxena (2015 Phys. Rev. Lett. 114 150601) showed that quantum Jarzynski equality generalizes to PT- symmetric quantum mechanics with unbroken symmetry. later Zeng and Yong (2017 Journal of Phys. Commun. 1 031001) extended this work to Crook's fluctuation theorem. In another recent paper, Andrew Smith et al 2018 discusses non-equilibrium work relation in open quantum system. In this paper, we will discuss the validity of non-Hermitian fluctuation theorem in open quantum system, in a region of unbroken PT- symmetry.
