Abstract
The entanglement between two identical two-level atoms successively passing the thermal cavity has been investigated taking into account the detuning. and Kerr nonlinarity We have derived that for thermal field the increasing of the mean photon number leads to decreasing of the entanglement, but the entanglement increases as the detuning or Kerr nonlinearity increases. For thermal field we have established that the effect of sudden death and birth of entanglement takes place and that for large detuning or Kerr nonlinearity vanishes.
