Abstract: The influence of dipole-dipole interaction on the entanglement between two atoms with different initial W-like states in Tavis-Cummings model with degenerate two-photon transitions has been investigated. The results show that the entanglement between two atoms can be increased by means of dipole-dipole interaction and for some initial states the sudden death effect can be weakened.
Keywords: two-atom model, degenerate two-photon transitions, dipole-dipole interaction, entanglement, sudden death of entanglement.
