Quantum Monte Carlo Calculations with Chiral Effective Field Theory Interactions
Quantum Monte Carlo Calculations with Chiral Effective Field Theory Interactions
We present the first quantum Monte Carlo (QMC) calculations with chiral effective field theory (EFT) interactions. To achieve this, we remove all sources of nonlocality, which hamper the inclusion in QMC calculations, in nuclear forces to next-to-next-to-leading order. We perform auxiliary-field diffusion Monte Carlo (AFDMC) calculations for the neutron matter …
