Entanglement fidelity for electron–electron interaction in strongly coupled semiclassical plasma and under external fields

Abstract

This letter presents the effects of AB-flux field and electric field on electron–electron interaction, encircled by a strongly coupled semiclassical plasma. We found that weak external fields are required to perpetuate a low-energy elastic electron–electron interaction in a strongly coupled semiclassical plasma. The entanglement fidelity in the interaction process has been examined. We have used partial wave analysis to derive the entanglement fidelity. We found that for a weak electric field, the fidelity ratio for electron–electron interaction increases as the projectile energy increases, but remains constant or almost zero for a strong electric field. Our results provide invaluable information on how the efficiency of entanglement fidelity for a low-energy elastic electron–electron interaction in a strongly coupled semiclassical plasma can be influenced by the presence of external fields.
