Entanglement in Three-Atom Tavis–Cummings Model Induced by a Thermal Field
Cai Jin-Fang, Liu Hui-Ping · Communications in Theoretical Physics · 2005
The explicit form of the evolution operator for the three-atom Tavis–Cummings model is given. The atoms can be entangled through their interaction with a thermal field. The degree of entanglement depends on the mean photon number of the thermal field and the initial state of the atoms.
