Phaseless quantum Monte-Carlo approach to strongly correlated superconductors with stochastic Hartree-Fock-Bogoliubov wavefunctions
Olivier Juillet, Alexandre Leprévost, Jérémy Bonnard +1
The so-called phaseless quantum Monte-Carlo method currently offers one of the best performing theoretical framework to investigate interacting Fermi systems. It allows to extract…
Constrained-Path Quantum Monte-Carlo Approach for Non-Yrast States Within the Shell Model
J. Bonnard, O. Juillet
The present paper intends to present an extension of the constrained-path quantum Monte-Carlo approach allowing to reconstruct non-yrast states in order to reach the complete spect…
Exact Ground State of Strongly Correlated Electron Systems from Symmetry-Entangled Wave-Functions
A. Leprévost, O. Juillet, R. Frésard
The four-site Hubbard model is considered from the exact diagonalisation and variational method points of view. It is shown that the exact ground-state can be recovered by a symmet…
A Constrained-Path Quantum Monte-Carlo Approach for the Nuclear Shell Model
Jérémy Bonnard, Olivier Juillet
A new Quantum Monte-Carlo (QMC) approach is proposed to investigate low-lying states of nuclei within the shell model. The formalism relies on a variational symmetry-restored wave-…
Exotic spin, charge and pairing correlations of the two-dimensional doped Hubbard model: a symmetry entangled mean-field approach
Olivier Juillet, Raymond Frésard
Intertwining of spin, charge and pairing correlations in the repulsive two-dimensional Hubbard model is shown through unrestricted variational calculations, with projected wavefunc…
Boundary conditions for star matter and other periodic fermionic systems
Francesca Gulminelli, Takuya Furuta, Olivier Juillet +1
Bulk fermionic matter, as it can be notably found in supernova matter and neutrons stars, is subject to correlations of infinite range due to the antisymmetrisation of the N-body w…
