Entanglement fidelity ratio for elastic collisions in non-ideal two-temperature dense plasma

Abstract

The quantum diffraction and symmetry effects on the entanglement fidelity (EF) of different elastic electron-electron, ion-ion and electron-ion interactions are investigated in non-ideal dense plasmas. The partial wave analysis, an effective screened interaction potential including quantum mechanical diffraction and symmetry effects are employed to obtain the EF in a nonideal dense plasma. We show that collision energy and temperatures of electron and ion have destructive effects on the entanglement in the system. In fact, by decreasing the temperature of plasma particles, the quantum effects become more prominent and the entanglement is elevated. Also, increase in the density of plasma leads to the enhancement of entanglement ratio. Additionally, some important characteristic parameters of the scattering such as differential, transport and total cross sections are calculated.

Laser beam effect on the entanglement of elastic collisions in quantum plasma

“…is the well-known Legendre polynomial of order l, while l is the angular momentum quantum number. For a spherically symmetric potential, it has been shown that the radial wave equation R l,k (r) and the expansion coefficient D l,k are given by [41,44]:…”

“…It is because of the presence of high density charged particles. It is clear that in such media, collective effects caused by the long range electromagnetic interactions play an important role and result in the quantum correlations between particles [44]. Presenting a successful definition of an appropriate potential, which includes all important features of interactions, is the first and most essential step in studying quantum entanglement in plasmas.…”
