The itinerant ferromagnetic phase of the Hubbard model
Giuseppe Carleo, Saverio Moroni, Federico Becca +1
Using a newly developed quantum Monte Carlo technique, we provide strong evidence for the stability of a saturated ferromagnetic phase in the high-density regime of the two-dimensi…
Reptation quantum Monte Carlo for lattice Hamiltonians with a directed-update scheme
Giuseppe Carleo, Federico Becca, Saverio Moroni +1
We provide an extension to lattice systems of the reptation quantum Monte Carlo algorithm, originally devised for continuous Hamiltonians. For systems affected by the sign problem,…
Size-consistent variational approaches to non-local pseudopotentials: standard and lattice regularized diffusion Monte Carlo methods revisited
Michele Casula, Saverio Moroni, Sandro Sorella +1
We propose improved versions of the standard diffusion Monte Carlo (DMC) and the lattice regularized diffusion Monte Carlo (LRDMC) algorithms. For the DMC method, we refine a schem…
