Fixed-phase approximation and Diffusion Quantum Monte Carlo
F. Delyon, B. Bernu
We present a simple approach to the fixed phase method in Quantum Monte Carlo. This applies to electrons in molecules and electron gas and is straightforwardly extended to the Schr…
Upper bounds of spin-density wave energies in the homogeneous electron gas
F. Delyon, B. Bernu, L. Baguet +1
Studying the jellium model in the Hartree-Fock approximation, Overhauser has shown that spin density waves (SDW) can lower the energy of the Fermi gas, but it is still unknown if t…
Properties of Hartree-Fock solutions of the three-dimensional electron gas
L. Baguet, F. Delyon, B. Bernu +1
In a previous letter, L. Baguet et al., (Phys. Rev. Lett. {\bf 111}, 166402 (2013)), we presented the ground state phase diagram of the homogeneous electron gas in three dimensions…
The Hartree-Fock phase diagram of the two-dimensional electron gas
B. Bernu, F. Delyon, M. Holzmann +1
We calculate the ground state phase diagram of the homogeneous electron gas in two dimensions within the Hartree-Fock approximation. At high density, we find stable solutions, wher…
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…
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…
