Finite and Infinite Matrix Product States for Gutzwiller Projected Mean-Field Wavefunctions
Gabriel Petrica, Bo-Xiao Zheng, Garnet Kin-Lic Chan +1
Matrix product states (MPS) and `dressed' ground states of quadratic mean fields (e.g. Gutzwiller projected Slater Determinants) are both important classes of variational wave-func…
Ground-state phase diagram of the three-band Hubbard model from density matrix embedding theory
Zhi-Hao Cui, Chong Sun, Ushnish Ray +3
We determine the ground-state phase diagram of the three-band Hubbard model across a range of model parameters using density matrix embedding theory. We study the atomic-scale natu…
Density Matrix Embedding Theory and Strongly Correlated Lattice Systems
Bo-Xiao Zheng
This thesis describes the development of the density matrix embedding theory (DMET) and its applications to lattice strongly correlated electron problems, including a review of DME…
Stripe order in the underdoped region of the two-dimensional Hubbard model
Bo-Xiao Zheng, Chia-Min Chung, Philippe Corboz +7
Competing inhomogeneous orders are a central feature of correlated electron materials including the high-temperature superconductors. The two- dimensional Hubbard model serves as t…
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…
Critical Branching Brownian Motion with Killing
Steven P. Lalley, Bowei Zheng
We obtain sharp asymptotic estimates for hitting probabilities of a critical branching Brownian motion in one dimension with killing at 0 We also obtain sharp asymptotic formulas f…
