Variational Monte Carlo Study of Electron Differentiation around Mott Transition
Daisuke Tahara, Masatoshi Imada
We study ground-state properties of the two-dimensional Hubbard model at half filling by improving variational Monte Carlo method and by implementing quantum-number projection and…

Variational Monte Carlo Method Combined with Quantum-Number Projection and Multi-Variable Optimization
Daisuke Tahara, Masatoshi Imada
Variational wave functions used in the variational Monte Carlo (VMC) method are extensively improved to overcome the biases coming from the assumed variational form of the wave fun…
