We show a right unitary transformation approach based on Susskind–Glogower operators that diagonalizes a generalized Dicke Hamiltonian in the field basis and delivers a tridiagonal Hamiltonian in the Dicke basis. This tridiagonal Hamiltonian is diagonalized by a set of orthogonal polynomials satisfying a three-term … showboat hotel atlantic city lounge

http://miguelbastarrachea.com/physics/physics-research/the-dicke-hamiltonian/ WebMay 14, 2024 · This is because the Dicke Hamiltonian, like the closely related BCS Hamiltonian is in the class of Gaudin–Richardson models [15]. Since the two-level systems in the original Dicke model couple to the radiation field, they are electric dipoles, and as such one should also consider direct electrostatic interactions 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.
