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…
