Single-Particle Spectral Function Formulated and Calculated by Variational Monte Carlo Method with Application to d-Wave Superconducting State
A method to calculate the one-body Green’s function for ground states of correlated electron materials is formulated by extending the variational Monte Carlo method. We benchmark against the exact diagonalization (ED) for the one- and two-dimensional Hubbard models of 16-site lattices, which proves...
