Hartree-Fock approximation for non-Coulomb interactions in three and two-dimensional systems
Year: 2024
Type: article
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.
