<Abstrcat>We investigate the time evolution of thermal entanglement between atom and single photon in Jaynes-Cummings model containing atomic motion by means of concurrence.

The dynamical behaviors of the entanglement for the excitons in a system of two coupled quantum dots and a single-mode cavity field are investigated for two different initial conditions by means of the concurrence.

The thermal entanglement of a two-level atom coupled to Single-mode cavity with the effect of virtual-photon field in nonresonant system by means of concurrence is investigated.

The concurrence decreased with increasing temperature.

Also the time evolution and the thermal entanglement of this model will be studied by the concept of concurrence in this paper.

we investigate the evolution of atom-cavity entanglement versus time in single-photon J-C model and two-photon J-C model by means of von Neumann entropy and concurrence,respectively;and at the same time, we find out the evolution law of entanglement versus time.

In this paper,we investigate the effects of temperature and anisotropy parameter on the entanglement resonance,and the evolution of concurrence for different length of the chain at finite temperatures is also studied.
