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…
Theory for the phase behaviour of a colloidal fluid with competing interactions
A. J. Archer, C. Ionescu, D. Pini +1
We study the phase behaviour of a fluid composed of particles which interact via a pair potential that is repulsive for large inter-particle distances, is attractive at intermediat…
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…
Rheology of colloidal microphases in a model with competing interactions
A. Imperio, L. Reatto, S. Zapperi
We study the rheological properties of colloidal microphases in two dimensions simulating a model of colloidal particles with competing interactions. Due to the competition between…
Liquid-vapor transition from a microscopic theory: Beyond the Maxwell construction
Alberto Parola, Davide Pini, Luciano Reatto
A smooth cut-off formulation of the Hierarchical Reference Theory (HRT) is developed and applied to a Yukawa fluid. The HRT equations are derived and numerically solved leading to:…
