Effects of high intensity Lasers on the Entanglement fidelity of quantum plasmas

The dynamics of entanglement during the low energy scattering processes in bipartite systems at the presence of a laser field is studied, using the Kramers-Henneberger unitary transformation as the semi classical counterpart of the Block-Nordsieck transformation, in the quantizied field formalism. The Stationary-state Schrodinger equation for quantum scattering process is obtained for such systems. Then, by using partial wave analysis, we introduce new form of entanglement fidelity containing high intense laser field. Therefore, the effective potential of hot quantum plasmas including plasmon and quantum screening effect is used to show entanglement fidelity ratio as a function of the laser amplitude, plasmon parameter and the Debye length parameter for elastic electron-ion collisions. It is shown that the amplitude of laser beam or free electron oscillation play important roles in the evolution of entanglement of the system.
