Waiting-times statistics in boundary driven free fermion chains

arXiv:2108.11850 · doi:10.1103/PhysRevB.104.195408

Abstract

We study the waiting-time distributions (WTDs) of quantum chains coupled to two Lindblad baths at each end. Our focus is on free fermion chains, where we derive closed-form expressions in terms of single-particle matrices, allowing one to study arbitrarily large chain sizes. In doing so, we also derive formulas for 2-point correlation functions involving non-Hermitian propagators.
