Automatic Order Detection and Restoration Through Systematically Improvable Variational Wave Functions
Ryan Levy, Miguel A. Morales, Shiwei Zhang
Variational wave function ansatze are an invaluable tool to study the properties of strongly correlated systems. We propose such a wave function, based on the theory of auxiliary f…
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…
Metal-insulator transition in transition metal dichalcogenide heterobilayer: accurate treatment of interaction
Yubo Yang, Miguel Morales, Shiwei Zhang
Transition metal dichalcogenide superlattices provide an exciting new platform for exploring and understanding a variety of phases of matter. The moiré continuum Hamiltonian, of tw…
Interfacing branching random walks with Metropolis sampling: constraint release in auxiliary-field quantum Monte Carlo
Zhi-Yu Xiao, Hao Shi, Shiwei Zhang
We present an approach to interface branching random walks with Markov chain Monte Carlo sampling, and to switch seamlessly between the two. The approach is discussed in the contex…
Non-perturbative Many-Body Treatment of Molecular Magnets
Brandon Eskridge, Henry Krakauer, Shiwei Zhang
Molecular magnets have received significant attention because of their potential applications in quantum information and quantum computing. A delicate balance of electron correlati…
Solving 2D and 3D lattice models of correlated fermions -- combining matrix product states with mean field theory
Gunnar Bollmark, Thomas Köhler, Lorenzo Pizzino +6
Correlated electron states are at the root of many important phenomena including unconventional superconductivity (USC), where electron-pairing arises from repulsive interactions.…
