Site occupation constraints in mean-field approaches of quantum spin systems at finite temperature

Raoul Dillenschneider, Jean Richert

We study the effect of site occupation on the description of quantum spin systems at finite temperature and mean-field level. We impose each lattice site to be occupied by a single…

Planar Voronoi cells and the failure of Aboav's law

Hendrik-Jan Hilhorst

Aboav's law is a quantitative expression of the empirical fact that in planar cellular structures many-sided cells tend to have few-sided neighbors. This law is nonetheless violate…

Fluctuations of internal energy flow in a vibrated granular gas

A. Puglisi, P. Visco, A. Barrat +2

The non-equilibrium fluctuations of power flux in a fluidized granular media have been recently measured in an experiment [Phys. Rev. Lett. 92, 164301, 2004], which was announced t…

Injected power and entropy flow in a heated granular gas

P. Visco, A. Puglisi, A. Barrat +2

Our interest goes to the power injected in a heated granular gas and to the possibility to interpret it in terms of entropy flow. We numerically determine the distribution of the i…

A van der Waals free energy in electrolytes revisited

B. Jancovici

A system of three electrolytes separated by two parallel planes is considered. Each region is described by a dielectric constant and a Coulomb fluid in the Debye-Hückel regime. In…

Internal space renormalization group for the Luttinger model

Janos Polonyi, Franck Stauffer

The absence of fermionic, asymptotical one-particle states in the Luttinger model raises the suspicion that the interactions are actually strong at the vicinity of the Fermi points…
