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.
