Interplay of dissipation and light-matter interaction in static and dynamical phases of a cavity-BEC system

Abstract

Dissipation, traditionally viewed as a source of decoherence, has served to stabilize a variety of non-equilibrium phases in quantum systems. Using an experimentally realizable atom-cavity model, we investigate how the interplay between light-matter coupling λ and dissipation κ of bosonic modes pushes the system through normal, superradiant, limit cycle, limit torus, and chaotic phases. Employing mean-field and truncated Wigner approximations, we construct a phase diagram in κ-λ parameter space, demonstrating that these experimentally tunable parameters provide precise control for observing quantum phases in driven-dissipative systems.
