Excitation spectrum in two-dimensional superfluid 4He
F. Arrigoni, E. Vitali, D. E. Galli +1
In this work we perform an ab-initio study of an ideal two-dimensional sample of 4He atoms, a model for 4He films adsorbed on several kinds of substrates. Starting from a realistic…

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…

Microscopic studies of solid 4He with Path Integral Projector Monte Carlo
M. Rossi, R. Rota, E. Vitali +2
We have investigated the ground state properties of solid He with the Shadow Path Integral Ground State method. This exact T=0 K projector method allows to describes quantum so…
