 , 2ème étage\, Bât 100\, Campus d'Orsay - 2 Oct 14 14:30
DESCRIPTION:Phase transitions in hard core lattice gas models of anisotropi
 c particles\nJoyjit Kundu\, Institute of Mathematical Sciences\, Chennai\n
 Hard core lattice gas models of particles interacting only through exclude
 d volume interaction continue to be of interest in Statistical Physics. Th
 ey are minimal models to study entropy driven phase transitions\, have dir
 ect realizations in adsorption of gas particles on metal surfaces and are 
 closely related to the freezing transition. In this talk\, I will discuss 
 the system of hard rectangles of size m x m k on a two dimensional lattice
 \, where k is the aspect ratio. The phase diagram of this model for arbitr
 ary m and k is determined using Monte-Carlo simulations\, entropic argumen
 ts\, and analytical calculations based on the Bethe approximation. In part
 icular\, it will be shown that\, with increasing density\,  the system un
 dergoes three entropy driven phase transitions for large enough k.
