- Abstract
- The Friedel screening effects on the entanglement fidelity for the elastic electron-ion collision are investigated in degenerate quantum collisional plasmas. The partial wave analysis and effective interaction including the far-field terms caused by the quantum screening and Kohn singularities are employed to obtain the entanglement fidelity function in dense quantum plasmas. It is found that the Friedel screening effects enhance the entanglement fidelity in quantum plasmas. It is also found that the entanglement fidelity decreases with increasing collision frequency. The Friedel screening effect is found to be more significant in small collision energy and high Fermi wave number domains.
