WebJun 7, 2024 · The modified Dicke Hamiltonian is extended to describe the effective of two-qubit model [31,32,33]. Recently, we studied a system of a two-level atom BEC coupled to a high-finesse optical cavity . Furthermore, we presented a simple model describing SR of the DM Hamiltonian using the HWl coherent states. WebWe show that a Dicke-type non-hermitian Hamiltonian admits entirely real spectra by mapping it tothe “Dressed Dicke Model”(DDM) through a similarity transformation. We ﬁnd a positive-deﬁnite metric in the Hilbert space of the non-hermitian Hamiltonian so that the time-evolution is unitary and allows a consistent quantum description. iran bans morality police
