Velocity dependent potential effects on two-electron quantum dot in plasmas

Abstract

In this study, for the first time, the effects of the velocity-dependent potential (VDP) on the energies of a two-electron parabolic quantum dot (TEPQD) in Debye and quantum plasma environments depicted by a more general exponential cosine screened Coulomb (MGECSC) potential are taken into consideration. The Schrödinger equation is modified by combining the MGECSC potential and VDP, solving numerically via the asymptotic iteration method. The Schrödinger equation with VDP is basically another type of one with position-dependent mass. The effects of VDP on two interacting electrons inside the parabolic quantum dot in plasmas are probed by considering the isotropic form factor with the harmonic (ρ(r)=ρ0r2) and constant (ρ(r)=ρ0) form. The alternativeness of the plasma shielding parameters to each other, the confinement parameter of the quantum dot, and the VDP parameters on energies and possible radiations of TEPQD are also discussed.
