Abstract
We investigate the entanglement dynamics of a quantum system consisting of
two two-level atoms in a cavity with classical driving fields in the presence of
white noise. The cavity is initially prepared in the vacuum state. Generally, the
entanglement of two atoms decreases with the intensity of the thermal fields and the
coupling strength of the two-level atoms to the thermal fields. However, we find
that the entanglement of the quantum system can be enhanced by adjusting the
frequency and the strength of the classical driving fields in the presence of white
noise.
