Abstract

We analyzed the Hartree-Fock approximation for an electron system. The interaction between particles is modeled by a non-Coulombian potential. We analyzed both the three-dimensional and two-dimensional systems. We obtained accurate analytical results for the particle energy, the particle velocity, the ground state energy of the system as well as the momentum dependent density of states. The previous classical results for the Coulombian case were reobtained as particular cases.

三维和二维系统中非库仑相互作用的哈特里-福克近似值

我们分析了电子系统的哈特里-福克近似。粒子之间的相互作用由非库仑势建模。我们分析了三维和二维系统。我们获得了粒子能量、粒子速度、系统基态能量以及与动量相关的状态密度的精确分析结果。作为特例，我们重新获得了之前库仑势情况下的经典结果。
