Dicke hamiltonian
The Dicke model is a fundamental model of quantum optics, which describes the interaction between light and matter. In the Dicke model, the light component is described as a single quantum mode, while the matter is described as a set of two-level systems. When the coupling between the light and matter … See more The Dicke model is a quantum mechanical model that describes the coupling between a single-mode cavity and $${\displaystyle N}$$ two-level systems, or equivalently $${\displaystyle N}$$ spin-½ degrees of freedom. The … See more The Dicke model of Eq. 1 assumes that the cavity mode and the two-level systems are perfectly isolated from the external environment. In actual experiments, this assumption is not … See more The Dicke model can be generalized by considering the effects of additional terms in the Hamiltonian of Eq. 1. For example, a recent experiment realized an open Dicke model with … See more • Jaynes–Cummings model • Superradiance • Superradiant phase transition See more Early studies of the Dicke model considered its equilibrium properties.
