Many-body computations by stochastic sampling in Hartree-Fock-Bogoliubov space
Hao Shi, Shiwei Zhang
We describe the computational ingredients for an approach to treat interacting fermion systems in the presence of pairing fields, based on path-integrals in the space of Hartree-Fo…
Cluster size convergence of the density matrix embedding theory and its dynamical cluster formulation: a study with an auxiliary-field quantum Monte Carlo solver
Bo-Xiao Zheng, Joshua S. Kretchmer, Hao Shi +2
We investigate the cluster size convergence of the energy and observables using two forms of density matrix embedding theory (DMET): the original cluster form (CDMET) and a new for…
Coupling quantum Monte Carlo and independent-particle calculations: self-consistent constraint for the sign problem based on density or density matrix
Mingpu Qin, Hao Shi, Shiwei Zhang
Quantum Monte Carlo (QMC) methods are one of the most important tools for studying interacting quantum many-body systems. The vast majority of QMC calculations in interacting fermi…
Computation of dynamical correlation functions for many fermion systems with auxiliary-field quantum Monte Carlo
Ettore Vitali, Hao Shi, Mingpu Qin +1
We address the calculation of dynamical correlation functions for many fermion systems at zero temperature, using the auxiliary-field quantum Monte Carlo method. The two-dimensiona…
Benchmark study of the two-dimensional Hubbard model with auxiliary-field quantum Monte Carlo method
Mingpu Qin, Hao Shi, Shiwei Zhang
Ground state properties of the Hubbard model on a two-dimensional square lattice are studied by the auxiliary-field quantum Monte Carlo method. Accurate results for energy, double…
Rashba spin-orbit coupling, strong interactions, and the BCS-BEC crossover in the ground state of the two-dimensional Fermi Gas
Hao Shi, Peter Rosenberg, Simone Chiesa +1
The recent experimental realization of spin-orbit coupled Fermi gases provides a unique opportunity to study the interplay between strong interaction and SOC in a tunable, disorder…
