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…
Algorithm for branching and population control in correlated sampling
Siyuan Chen, Yiqi Yang, Miguel Morales +1
Correlated sampling has wide-ranging applications in Monte Carlo calculations. When branching random walks are involved, as commonly found in many algorithms in quantum physics and…
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…
Ab initio investigation of the crystallization mechanism of cadmium selenide
Linshuang Zhang, Manyi Yang, Shiwei Zhang +1
Cadmium selenide (CdSe) is an inorganic semiconductor with unique optical and electronic properties that made it useful in various applications, including solar cells, light-emitti…
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…
