Paper Abstract

We study the entanglement properties of a pair of two-level atoms going through a thermal cavity one after another. The initial joint states of two successive atoms that enter the cavity are coherent or entangled. Using the exact solution of density matrix evolution equation we calculated the negativity for different values of cavity mean photon numbers. We shown the possibility to save the initial atomic entanglement even for a thermal cavity field with relatively high temperature.
