[HTML][HTML] Hartree-Fock approximation for non-Coulomb interactions in three and two-dimensional systems

VM Ene, I Lianu, I Grosu - Physics Letters A, 2025 - Elsevier
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 …

Image forces for a point-like dipole near a plane metal surface: An account of the spatial dispersion of dielectric permittivity

AM Gabovich, MS Li, H Szymczak, AI Voitenko - Surface science, 2012 - Elsevier

dispersionless semi-infinite medium adjacent to a medium with the spatial dispersion of its …

Screening of a single impurity and Friedel oscillations in Fermi liquids

B Chatterjee, K Byczuk - Journal of Physics: Conference Series, 2015 - iopscience.iop.org
Abstract We numerically study Friedel Oscillations and screening effect around a single
impurity in one-and two-dimensional interacting lattice electrons. The interaction between …

Impurities and other defects in correlated lattice electrons: Friedel oscillations and interference patterns

B Chatterjee, J Skolimowski, K Byczuk - Physical Review B, 2022 - APS
We study interference patterns and Friedel oscillations (FO) due to scattering from two or
more localized impurities and scattering from extended inhomogeneities in the two …

CONDUCTANCE OF AN ONE AND DOUBLE-LEVEL QUANTUM DOT

I GROSU - Studia Universitatis Babeș-Bolyai Physica, 2022 - 193.231.18.162
We analytically study the expression of the electric charge current through a two-terminal
quantum dot in the linear response approximation. We analyse the one-level and the two …

FRIEDEL OSCILLATIONS IN A ONE-DIMENSIONAL NON-INTERACTING ELECTRON GAS IN THE PRESENCE OF TWO IMPURITIES.
