Abstract: The Dicke Hamiltonian is a paradigmatic model of quantum optics that describe the ultra-strong coupling between light and collective modes of matter. This interaction results in the creation of polaritons, hybrid quantum states that share properties of their original components. Originally proposed to describe atoms in cavities, the model has now become a general formulation of the spin-boson interaction with applications in polariton physics and various systems within the context of quantum information, atomic physics, and condensed matter. In this talk, I will address the model’s theoretical richness for exploring the quantum-classical correspondence. Thanks to its collective nature, it is possible to easily identify a classical counterpart and use quantum localization techniques to probe, identify, and quantify structures in phase space, regularity, and chaos, establishing a route to explore other, more complex, interacting quantum systems.
