Dicke hamiltonian
The Hamiltonian that describes the full system, Here, for convenience, the vacuum field energy is set to . For deriving the JCM interaction Hamiltonian the quantized radiation field is taken to consist of a single bosonic mode with the field operator , where the operators and are the bosonic creation and annihilation operators and is the angular frequency of the mode. On the other hand, the two-leve… WebJul 19, 2011 · We show that semiclassical states adapted to the symmetry of the Hamiltonian are an excellent approximation to the exact quantum solution of the ground and first excited states of the Dicke model. Their overlap with the exact quantum states is very close to 1 except in a close vicinity of the quantum phase transition. Furthermore, …
