In the quantized field formalism,using Kramers-Henneberger unitary transformation as the semi-classical counterpart of Block-Nordsieck transformation,the dynamics of entanglement during the low energy scattering processes in bi-partite systems at the presence of a laser beam fields are studied.The stationary-state Schrodinger equation for the quantum scattering process is obtained for such systems.Then,using partial wave analysis,we introduce a new form of entanglement fidelity considering the effect of high-intensity laser beam fields.The effective potential of hot quantum plasma including plasmon and quantum screening effects is used to obtain the entanglement fidelity ratio as a function of the laser amplitude,and plasmon and Debye length parameters for the elastic electron-ion collisions.It is shown that the plasma free electrons oscillations under interaction with laser beam fields improve the correlations between charged particles and consequently lead to the increase in the system entanglement.
