Validity of non-Hermitian fluctuation theorem in open Quantum system with unbroken PT- symmetry
Saurov Hazarika
TL;DR
This paper investigates whether the non-Hermitian fluctuation theorem holds in open quantum systems that exhibit unbroken PT-symmetry, extending previous work on quantum fluctuation relations.
Contribution
It analyzes the validity of the non-Hermitian fluctuation theorem specifically within open quantum systems with unbroken PT-symmetry, filling a gap in current understanding.
Findings
Confirms the validity of the non-Hermitian fluctuation theorem in unbroken PT-symmetric open quantum systems.
Extends previous results on quantum fluctuation theorems to a broader class of non-Hermitian systems.
Provides theoretical insights into non-equilibrium quantum thermodynamics in PT-symmetric systems.
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.
