Monte Carlo Methods in the Manifold of Hartree-Fock-Bogoliubov Wave Functions
Ettore Vitali, Peter Rosenberg, Shiwei Zhang
We explore the possibility to implement random walks in the manifold of Hartree-Fock-Bogoliubov wave functions. The goal is to extend state-of-the-art quantum Monte Carlo approache…
Metal-insulator transition and quantum magnetism in the SU(3) Fermi-Hubbard Model: Disentangling Nesting and the Mott Transition
Chunhan Feng, Eduardo Ibarra-García-Padilla, Kaden R. A. Hazzard +3
We use state-of-the-art numerical techniques to compute ground state correlations in the two-dimensional SU(3) Fermi Hubbard model at -filling, modeling fermions with three po…
Stripes and spin-density waves in the doped two-dimensional Hubbard model: ground state phase diagram
Hao Xu, Hao Shi, Ettore Vitali +2
We determine the spin and charge orders in the ground state of the doped two-dimensional (2D) Hubbard model in its simplest form, namely with only nearest-neighbor hopping and on-s…
Exotic Superfluid Phases in Spin Polarized Systems on Optical Lattices
Ettore Vitali, Peter Rosenberg, Shiwei Zhang
Leveraging cutting-edge numerical methodologies, we study the ground state of the two-dimensional spin-polarized Fermi gas in an optical lattice. We focus on systems at high densit…
Fermionic Superfluidity: From Cold Atoms to Neutron Stars
Annette Lopez, Patrick Kelly, Kaelyn Dauer +1
From flow without dissipation of energy to the formation of vortices when placed within a rotating container, the superfluid state of matter has proven to be a very interesting phy…
Magnetic and charge orders in the ground state of the Emery model -- accurate numerical results
Adam Chiciak, Ettore Vitali, Shiwei Zhang
We perform extensive auxiliary-field quantum Monte Carlo (AFQMC) calculations for the three-band Hubbard (Emery) model in order to study the ground-state properties of Copper-Oxyge…
