Imaginary chemical potential quantum Monte Carlo for Hubbard molecules
Fei Lin, Jurij Smakov, Erik S. Sorensen +2
We generalize the imaginary chemical potential quantum Monte Carlo (QMC) method proposed by Dagotto et al. [Phys. Rev. B 41, R811 (1990)] to systems without particle-hole symmetry.…

QMC Calculation of the Electronic Binding Energy in a C60 Molecule
Fei Lin, Jurij Smakov, Erik S. Sorensen +2
Electronic energies are calculated for a Hubbard model on the molecule using projector quantum Monte Carlo (QMC). Calculations are performed to accuracy high enough to det…
