Quantum Monte Carlo Algorithm Based on Two-Body Density Functional Theory for Fermionic Many-Body Systems: Application to 3He
Balazs Hetenyi, L. Brualla, S. Fantoni
We construct a quantum Monte Carlo algorithm for interacting fermions using the two-body density as the fundamental quantity. The central idea is mapping the interacting fermionic…

Higher order and infinite Trotter-number extrapolations in path integral Monte Carlo
L. Brualla, K. Sakkos, J. Boronat +1
Improvements beyond the primitive approximation in the path integral Monte Carlo method are explored both in a model problem and in real systems. Two different strategies are studi…

Spin-orbit induced backflow in neutron matter with auxiliary field diffusion Monte Carlo
L. Brualla, S. Fantoni, A. Sarsa +2
The energy per particle of zero-temperature neutron matter is investigated, with particular emphasis on the role of the interaction. An analysis of the importan…
