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…
Zero-temperature study of vacancies in solid 4He
M. Rossi, E. Vitali, D. E. Galli +1
We are investigating the properties of vacancies in solid 4He with the exact zero temperature SPIGS method. Our aim is to study the possibility of phase--separation between vacanci…
Zero-point vacancies in quantum solids
M. Rossi, E. Vitali, D. E. Galli +1
A Jastrow wave function (JWF) and a shadow wave function (SWF) describe a quantum solid with Bose--Einstein condensate; i.e. a supersolid. It is known that both JWF and SWF describ…
Path Integral Ground State study of 2D solid 4He
E. Vitali, M. Rossi, F. Tramonto +2
We have studied a two-dimensional triangular commensurate crystal of 4He with the exact T=0 K Path Integral Ground State (PIGS) Monte Carlo method. We have projected onto the true…
