Classical and Quantum Properties of the Spin-Boson Dicke Model: Chaos, Localization, and Scarring

This review article describes major advances associated with the Dicke model, starting in the 1950s when it was introduced to explain the transition from a normal to a superradiant phase. Since then, this spin-boson interacting model has raised significant theoretical and experimental interest in various contexts. The present review focuses on the isolated version of the model and covers properties and phenomena that are better understood when seen from both the classical and quantum perspectives, in particular, the onset of chaos, localization, and scarring.
