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 simplest realization of the Dicke model involves the dipole coupling between two-level atoms in a cavity. In this system, the observation of the superradiant transition is hindered by two possible problems: (1) The bare coupling between atoms and … See more Early studies of the Dicke model considered its equilibrium properties. These works considered the limit of $${\displaystyle N\to \infty }$$ (also known as the … See more Semiclassical limit A phase space for the Dicke model in the symmetric atomic subspace with $${\displaystyle S=N/2}$$ may be constructed by considering the tensor product of the Glauber coherent states q , p ⟩ = D ( q , p ) … 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 … See more • Jaynes–Cummings model • Superradiance • Superradiant phase transition See more WebJan 9, 2012 · To do so, we exploit the SU (4)-symmetry of the respective Lindblad operator and construct basis states that generalize the well-known Dicke states. This allows us to …
