Abstract

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.

Jayson Cosme is a theoretical physicist working at the interface between quantum optics and condensed matter physics. He earned his PhD in Physics at Massey University, New Zealand, where he studied several dynamical phenomena in quantum many-body systems including quench dynamics of a Bose-Einstein condensate and quantum thermalisation of isolated bosons. He moved to the University of Hamburg, Germany as a postdoctoral scientist to continue his research on nonequilibrium physics in various condensed matter platforms. He returned to the Philippines to join the National Institute of Physics at the University of the Philippines Diliman as an associate professor. His recent work focuses on dynamical phases of matter, such as time crystals, in cold atoms and superconductors.
