Absence of a Spin Liquid Phase in the Hubbard Model on the Honeycomb Lattice
Sandro Sorella, Yuichi Otsuka, Seiji Yunoki
A spin liquid is a novel quantum state of matter with no conventional order parameter where a finite charge gap exists even though the band theory would predict metallic behavior.…
Variational wave functions for frustrated magnetic models
Federico Becca, Luca Capriotti, Alberto Parola +1
Variational wave functions containing electronic pairing and suppressed charge fluctuations (i.e., projected BCS states) have been proposed as the paradigm for disordered magnetic…
From magnetism to one-dimensional spin liquid in the anisotropic triangular lattice
Dariush Heidarian, Federico Becca, Sandro Sorella
We investigate the anisotropic triangular lattice that interpolates from decoupled one-dimensional chains to the isotropic triangular lattice and has been suggested to be relevant…
Exact Jastrow-Slater wave function for the one-dimensional Luttinger model
Benjamin Tayo, Sandro Sorella
We show that it is possible to describe the ground state of the Luttinger model in terms of a Jastrow-Slater wave function. Moreover, our findings reveal that one-particle excitati…
Role of backflow correlations for the non-magnetic phase of the t-t' Hubbard model
Luca F. Tocchio, Federico Becca, Alberto Parola +1
We introduce an efficient way to improve the accuracy of projected wave functions, widely used to study the two-dimensional Hubbard model. Taking the clue from the backflow contrib…
Stable liquid Hydrogen at high pressure by a novel ab-initio molecular dynamics
Claudio Attaccalite, Sandro Sorella
We introduce an efficient scheme for the molecular dynamics of electronic systems by means of quantum Monte Carlo. The evaluation of the (Born-Oppenheimer) forces acting on the ion…
