Modulating entanglement dynamics of two V-type atoms in dissipative cavity by detuning and weak measurement reversal

It is studied how to modulate entanglement dynamics of two V-type atoms in dissipative cavity by detuning, weak measurement and weak measurement reversal. The analytical solution of this model is obtained by solving Schr & ouml;dinger equation after diagonalizing Hamiltonian of dissipative cavity. It is discussed in detail how the entanglement dynamics is influenced by cavity-reservoir coupling, spontaneously generated interference (SGI) parameter, detuning between cavity with reservoir and weak measurement reversal. The results show that the entanglement dynamics of different initial states obviously depends on coupling, SGI parameter, detuning and reversing measurement strength. The stronger coupling, the smaller SGI parameter, the larger detuning and the bigger reversing measurement strength can all not only protect but also generate the entanglement, and the detuning is more effectively in the strong coupling regime than the weak measurement reversal, which is more effectively than the SGI parameter. We also provide the physical interpretations for these results.
