WebEach CPU has several power modes, which are collectively called "C-states" or "C-modes." In this article, we explain what these modes are, what they do, and which processors … 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.
