Exact ground state Monte Carlo method for Bosons without importance sampling
M. Rossi, M. Nava, L. Reatto +1
Generally ``exact'' Quantum Monte Carlo computations for the ground state of many Bosons make use of importance sampling. The importance sampling is based, either on a guiding func…

Quantum dislocations: the fate of multiple vacancies in two dimensional solid 4He
M. Rossi, E. Vitali, D. E. Galli +1
Defects are believed to play a fundamental role in the supersolid state of 4He. We have studied solid 4He in two dimensions (2D) as function of the number of vacancies n_v, up to 3…

Ab-initio low-energy dynamics of superfluid and solid 4He
E. Vitali, M. Rossi, L. Reatto +1
We have extracted information about real time dynamics of 4He systems from noisy imaginary time correlation functions f(tau) computed via Quantum Monte Carlo (QMC): production and…
