Abstract
The plasmon and screening effects on the entanglement fidelity for the elastic electron-ion collision are investigated in hot quantum plasmas. The partial wave analysis and effective interaction including the plasmon couplings are employed to obtain the entanglement fidelity function in hot quantum plasmas. It is shown that the plasmon effect enhances the entanglement fidelity in quantum plasmas for 0 < beta(equivalent to h omega(p)/k(B)T) < 0.8 and, however, suppresses the entanglement fidelity for 0.8 < beta < 1, where omega(p) is the plasmon frequency, k(B) is the Boltzmann constant, and T is the plasma temperature. It is also found that the entanglement fidelity decreases with increasing Debye length and collision energy. (C) 2011 American Institute of Physics. [doi:10.1063/1.3660799]
