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

TL;DR

This study investigates how external electric and AB-flux fields influence entanglement fidelity during low-energy electron-electron interactions in strongly coupled semiclassical plasmas, revealing that weak fields enhance fidelity with energy.

Contribution

It introduces a partial wave analysis approach to quantify entanglement fidelity in plasma interactions under external fields, highlighting the effects of field strength on fidelity behavior.

Findings

Weak external fields sustain low-energy elastic interactions.

Fidelity increases with projectile energy under weak electric fields.

Strong electric fields keep fidelity near zero regardless of energy.

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 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 increase as projectile energy increase but remains constant or almost zero for a strong electric field. Our results provide an 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.
