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:…
Smooth cutoff formulation of hierarchical reference theory for a scalar phi4 field theory
Cristian D. Ionescu, Alberto Parola, Davide Pini +1
The phi4 scalar field theory in three dimensions, prototype for the study of phase transitions, is investigated by means of the hierarchical reference theory (HRT) in its smooth cu…
Quasi One-Dimensional Bosons in Three-dimensional Traps: From Strong Coupling to Weak Coupling Regime
Luca Salasnich, Alberto Parola, Luciano Reatto
We analyze a recent experiment on a Tonks-Girardeau gas of Rb atoms (T. Kinoshita, T. Wenger, and D.S. Weiss, Science {\bf 305}, 1125 (2004)). We find that the experimental…
Condensate Fraction of a Fermi Gas in the BCS-BEC Crossover
Luca Salasnich, Nicola Manini, Alberto Parola
We investigate the Bose-Einstein condensation of Fermionic pairs in a uniform two-component Fermi gas obtaining an explicit formula for the condensate density as a function of the…
A microscopic approach to critical phenomena at interfaces: an application to complete wetting in the Ising model
Alberto Orlandi, Alberto Parola, Luciano Reatto
We study how the formalism of the Hierarchical Reference Theory (HRT) can be extended to inhomogeneous systems. HRT is a liquid state theory which implements the basic ideas of Wil…
Transition from 3D to 1D in Bose Gases at Zero Temperature
L. Salasnich, A. Parola, L. Reatto
We investigate the effects of dimensional reduction in Bose gases induced by a strong harmonic confinement in the transverse cylindric radial direction. By using a generalized Lieb…
