Collective and Screening Effects on Entanglement Fidelity in Elastic Collisions in Nonideal Plasmas

Abstract

The nonideal collective and plasma screening effects on the entanglement fidelity in elastic collisions are investigated in classical nonideal plasmas. The entanglement fidelity in nonideal plasmas is obtained as a function of the nonideality plasma parameter, Debye length, and collision energy. It is found that the plasma screening effect significantly increases the entanglement fidelity, especially for low collision energies. The entanglement fidelity is found to decrease with increasing collision energy. It is also found that the collective effect enhances the entanglement fidelity in nonideal plasmas.

Electron-exchange and quantum screening effects on the collisional entanglement fidelity in degenerate quantum plasmas

“…} −1 increases with decreasing scaled Debye length ¯ (≡ /a Z ) is the scaled impact parameter, a Z (= a 0 /Z ) is the Bohr radius of the hydrogenic ion with nuclear charge Z e. Hence, it would be expected that the plasma shielding effect increases the entanglement collisional R Y , especially for low-energy collisions. This result is identical to the case of the collisional entanglement fidelity in non-ideal plasmas [26] with the zero case of the non-ideality plasma parameter.…”

“…Hence, we have found the Fermi pressure, Bohm diffusion and quantum screening effects enhance the collisional entanglement fidelity in quantum plasmas. In addition, for the case of the Yukawa potential V Y (r ) = −(Z e 2 /r ) e −r/ , where is the Debye length, the Yukawa collisional entanglement fidelity ratio [26]…”

“…where, D l (k) is the expansion coefficient, i is the pure imaginary number, R l (r) is the solution of the radial wave equation, q P cos l ( ) is the Legendre polynomial of order l, and l is the angular momentum quantum number. For a spherically symmetric potential V(r), it has been shown that the radial wave equation and the expansion coefficient D l (k) are given by [42,45]…”

“…For the first time, Chang and Jung [45] theoretically studied the non-ideal collective and plasma screening effects on the EF of the low-energy electron-ion elastic collisions in the classical non-ideal plasma. Taking into account the nonthermal classical plasma with Lorentzian (kappa) distribution, the entanglement problem for the elastic electron-ion scattering are investigated by Shin and Jung [46].…”

“…The EF of various types of interaction potentials has been calculated [66][67][68][69] for a charged particles elastic scattering process. Falaye et al [43] have investigated the EF of elastic scattering at the presence of an external constant magnetic field.…”
