Time Evolution of Atom-Cavity Entanglement and Thermal Entanglement in a Nonresonant System

LI Yu-liangDept.of Physics and Electronic Information Engineering,Minjiang University, Fuzhou 350108,China  
Atomic-cavity entanglement in time evolution and thermal entanglement by means of concurrence are investigated for two-level atom system in cavity.The result shows that the atom-cavity maximal entangled state appears at the T=0,if it is Δ=0 or Δ=2g.There exists a critical temperature T_c=1.134gk,which is independent of a detuning frequency Δ.The thermal entanglement vanishes at the TT_c.and it decreases with the increasing of temperature at the TT_c.
