WebMay 10, 2024 · As Dicke states form a basis, I would expect the possibility to write uniquely any spin state in this basis. However, this is not possible as the basis has degenerate vectors. It seems that initial information on the symmetry under particle exchange is lost in this basis change.

http://muchong.com/html/200808/920460.html Like any other model in quantum mechanics, the Dicke model includes a set of quantum states (the Hilbert space) and a total-energy operator (the Hamiltonian). The Hilbert space of the Dicke model is given by (the tensor product of) the states of the cavity and of the two-level systems. See more 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 … 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 simplest realization of the Dicke model involves the dipole coupling between two-level atoms in a cavity.
