Abstract

This paper 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 requiredto perpetuate a low-energy elastic electron-electron interaction in a strongly coupled semiclassicalplasma. The entanglement fidelity in the interaction process has been examined. We have usedpartial wave analysis to derive the entanglement fidelity. We found that for a weak electric field,the fidelity ratio for electron-electron interaction increase as projectile energy increase but remainsconstant or almost zero for a strong electric field. Our results provide an invaluable information onhow the efficiency of entanglement fidelity for a low-energy elastic electron-electron interaction in astrongly coupled semiclassical plasma can be influenced by the presence of external fields.PACS numbers: 52.25.Kn, 52.27.Gr, 52.27.Lw, 52.25.Fi.
