We have numerically computed the exact distribution of zeros of the partition function for the ${\mathit{Z}}_{5}$-symmetric spin model on square lattices of linear size 3\ensuremath{\le}L\ensuremath{\le}7. At a point of the phase diagram close to the

We report on the low-temperature magnetic susceptibilities and specific heats of the isostructural spin-ladder molecular complexes L$_{2}$[M(opba)]$_{3\cdot x$DMSO$\cdot y$H$_{2}$O, hereafter abbreviated with L$_{2}$M$_{3}$ (where L = La, Gd, Tb, Dy,

We analyse a specific two dimensional mixed spin Heisenberg model with exchange anisotropy, by means of high temperature expansions and Monte Carlo simulations. The goal is to describe the magnetic properties of the compound (NBu_{4})_{2}Mn_{2}[Cu(op

RANDOM SEQUENTIAL ADSORPTION ON A DASHED LINE

Autor: B. Bonnier, E. Pommiers, Y. Leroyer

We study analytically and numerically a model of random sequential adsorption (RSA) of segments on a line, subject to some constraints suggested by two kinds of physical situations: - deposition of dimers on a lattice where the sites have a spatial e

We study the deposition of line segments on a two-dimensional square lattice. The estimates for the coverage at jamming obtained by Monte-Carlo simulations and by $7^{th}$-order time-series expansion are successfully compared. The non-trivial limit o
