Metal-insulator transition in the Hartree-Fock phase diagram of the fully polarized homogeneous electron gas in two dimensions
B. Bernu, F. Delyon, M. Duneau +1
We determine numerically the ground state of the two-dimensional, fully polarized electron gas within the Hartree-Fock approximation without imposing any particular symmetries on t…
Renormalization factor and effective mass of the two-dimensional electron gas
Markus Holzmann, Bernard Bernu, Valerio Olevano +2
We calculate the momentum distribution of the Fermi liquid phase of the homogeneous, two-dimensional electron gas. We show that, close to the Fermi surface, the momentum distributi…
Existence of a metallic phase and upper bounds of the Hartree-Fock energy in the homogeneous electron gas
F. Delyon, M. Duneau, B. Bernu +1
We consider the ground state of the homogeneous electron gas and we prove that a Hartree-Fock solution, motivated by previous simulations, has lower energy than the Fermi gas in th…
Metal-insulator transition in the two-dimensional fully polarized homogeneous electron gas from Hartree-Fock solutions
B. Bernu, F. Delyon, M. Duneau +1
We determine the ground state of the two-dimensional, fully polarized electron gas within the Hartree-Fock approximation without imposing any particular symmetries on the solutions…
