Dissipative phase transition in a one-dimensional circuit QED lattice: Theory
ORAL
Abstract
Our theoretical and experimental work indicate the occurrence of a dissipative phase transition in a linear chain composed of coupled microwave resonators and superconducting qubits. Studies of circuit QED lattices, therefore, have great potential for advancing our understanding of nonequilibrium many-body physics of light. Motivated by the experimental results, we present theory investigating the physics of a driven damped circuit-QED chain. Within mean-field approximation taking into account single-site driving and finite size of the chain, we numerically explore basic features of the transition observed when increasing the drive strength beyond a critical threshold.
