The effect of dipole-dipole interaction for two atoms with different couplings in non-Markovian environment
arXiv:0810.5420 · doi:10.1103/PhysRevA.79.012309
Abstract
Using the nonperturbative method, we study the exact entanglement dynamics of two two-level dipole-dipole interacting atoms coupled to a common non-Markovian reservoir with different coupling strengths. Besides analyzing the conditions for the existence of steady state, we find, though the dipole-dipole interaction could destroy the stationary entanglement, that relatively strong dipole-dipole interaction does suppress the disentanglement in the initial period of time. These results are helpful for the practical engineering of the entanglement in the future.
