Insulating and metallic phases in the one-dimensional Hubbard-Su-Schrieffer-Heeger model: Insights from a backflow-inspired variational wave function
Davide Piccioni, Francesco Ferrari, Michele Fabrizio +1
The interplay between electron-electron and electron-phonon interactions is studied in a one-dimensional lattice model, by means of a variational Monte Carlo method based on genera…

A Jastrow wave function for the spin-1 Heisenberg chain: the string order revealed by the mapping to the classical Coulomb gas
Davide Piccioni, Christian Apostoli, Federico Becca +4
We show that a two-body Jastrow wave function is able to capture the ground-state properties of the antiferromagnetic Heisenberg chain with the single-ion anisotropy term, in…
