Driven-dissipative three-level Dicke model in an atom-cavity system
The Dicke model is one of the paradigmatic models in the physics of light-matter interaction. It describes a system of two-level atoms interacting with a single light mode. Its extension is motivated by phenomena unique to three-level systems, such as lasing without inversion and subradiance. In our recent work, we investigate a driven-dissipative three-level Dicke model. I will discuss its unequivocal signatures, namely the emergence of an incommensurate time crystalline phase and light-induced or light-enhanced superradiance. I will also present experimental results, which demonstrate a quantum simulation of our proposed three-level Dicke model using a shaken atom-cavity system.
