2014/12/18
We show that Monte Carlo sampling of the Feynman diagrammatic series (DiagMC) can be used for tackling hard fermionic quantum many-body problems in the thermodynamic limit by presenting accurate resul...

Energies of the first row quantum Monte Carlo
2010/11/24
All-electron variational and diffusion quantum Monte Carlo calculations of the ground state energies of the first row atoms (Li to Ne) are reported. We use trial wavefunctions of four types:single det...
The Density of States and Band Gap of Liquid Water by Sequential Monte Carlo/Quantum Mechanics Calculations
Liquid Water Sequential Monte Carlo/Quantum Mechanics Calculations DOS EG
2010/10/18
Electronic properties of liquid water were investigated by sequential Monte Carlo/Quantum mechanics calculations. The density of states (DOS) and HOMO-LUMO gap (EG) of liquid water have been determine...
