Steady-state phases of the non-equilibrium Rabi-Hubbard Model

ORAL

Abstract

We study the realization of a tunable Rabi-Hubbard Model with a coupled cavity array containing Raman-pumped 4-level qubits. This effective model is found to display a phase diagram that features a normal phase (vanishing polarization and photon coherence) and a finite-frequency ordered phase. The ordered phase may either display a ``ferro-electric'' order where the photon coherence is uniform through the array, or one with an alternating phase that we refer to as ``anti-ferroelectric.''
