Metal-insulator transition and quantum magnetism in the SU (3) Fermi-Hubbard model
We develop a self-consistent variant of the constrained path quantum Monte Carlo approach
which ensures its independence of the trial wave function, and apply the method to compute …

Attractive Su-Schrieffer-Heeger-Hubbard model on a square lattice away from half-filling
The Su-Schrieffer-Heeger (SSH) model, with bond phonons modulating electron tunneling,
is a paradigmatic electron-phonon model that hosts an antiferromagnetic order to bond …

Enhancement of charge density wave correlations in a Holstein model with an anharmonic phonon potential
The Holstein Hamiltonian describes itinerant electrons whose site density couples to local
phonon degrees of freedom. In the single-site limit, at half filling, the electron-phonon …
