Statistical and computational intelligence approach to analytic continuation in Quantum Monte Carlo
G. Bertaina, D. E. Galli, E. Vitali
The term analytic continuation emerges in many branches of Mathematics, Physics, and, more generally, applied Science. Generally speaking, in many situations, given some amount of…
Low-density phases of He monolayers adsorbed on graphite
Michele Ruggeri, Ettore Vitali, Davide Emilio Galli +2
Quantum Monte Carlo simulations at zero temperature of a He monolayer adsorbed on graphite, either clean or preplated with He, unexpectedly point to a gas-liquid phase tran…
Study of solid 4He in two dimensions. The issue of zero-point defects and study of confined crystal
M. Rossi, L. Reatto, D. E. Galli
Defects are believed to play a fundamental role in the supersolid state of 4He. We report on studies by exact Quantum Monte Carlo (QMC) simulations at zero temperature of the prope…
Equation of state of two--dimensional He at zero temperature
M. Nava, E. Vitali, A. Motta +2
We have performed a Quantum Monte Carlo study of a two-dimensional bulk sample of interacting 1/2-spin structureless fermions, a model of He adsorbed on a variety of preplated…
Solid 4He and the Supersolid Phase: from Theoretical Speculation to the Discovery of a New State of Matter? A Review of the Past and Present Status of Research
D. E. Galli, L. Reatto
The possibility of a supersolid state of matter, i.e., a crystalline solid exhibiting superfluid properties, first appeared in theoretical studies about forty years ago. After a lo…
Two-body correlations and the superfluid fraction for nonuniform systems
Wayne M. Saslow, Davide E. Galli, Luciano Reatto
We extend the one-body phase function upper bound on the superfluid fraction in a periodic solid (a spatially ordered supersolid) to include two-body phase correlations. The one-bo…
