Comparison of Entanglement Sudden Death and Revival Between Independent and Coherent Double Pathways

Starting from famous Schr\"{o}dinger equation within the framework of semi-classical theory of light-matter interaction, we firstly obtain the analytical non-resonant solutions of the driven bipartite system's entanglement dynamics in independent and coherent double pathways. Numerical simulations show that under non-resonant condition, entanglement sudden death and revival between these transition patterns behave quite differently, indicating the utmost importance of transition pathways' interference. Furthermore, the laser pulse's area and detuning exert significant but quite distinct influences on the entanglement dynamics. Our analyses are helpful in manipulating entanglement in current experimental technology.
