The entanglement property between two two-level atoms interacting with a stochastic field is studied. We analytically prove that when the correlation time κ −1 of the stochastic field is very short compared to the radiative lifetime γ −1 of the atom, the steady-state entanglement between the two atoms can appear. The concurrence characterizing the entanglement degree has also been calculated by using Monte Carlo simulation. It is shown that the correlation time has a strong effect on the entanglement. We also discuss the influence of strength of the stochastic process on the entanglement. The validity of the decorrelation approximation is also investigated.
