Quench dynamics of a disordered array of dissipative coupled cavities

TL;DR

This paper studies how dissipation and disorder influence the evolution and coherence of photons in coupled cavity arrays, revealing signatures of many-body phases through emission properties.

Contribution

It introduces a mean-field approach to analyze the dynamics of disordered, dissipative cavity arrays and links emission coherence to many-body phases.

Findings

Dissipation and disorder significantly affect photon coherence.

Emission properties can indicate the system's many-body phase.

The dynamics depend on initial Fock state preparation.

Abstract

We investigate the mean-field dynamics of a system of interacting photons in an array of coupled cavities in presence of dissipation and disorder. We follow the evolution of on an initially prepared Fock state, and show how the interplay between dissipation and disorder affects the coherence properties of the cavity emission and that these properties can be used as signatures of the many-body phase of the whole array.
