Three-dimensional Ising model confined in low-porosity aerogels: a Monte Carlo study
Ricardo Paredes, Carlos Vasquez
The influence of correlated impurities on the critical behaviour of the 3D Ising model is studied using Monte Carlo simulations. Spins are confined into the pores of simulated aero…
Nematic phase transitions in two-dimensional systems
Bertrand Berche, Ricardo Paredes
Simulations of nematic-isotropic transition of liquid crystals in two dimensions are performed using an O(2) vector model characterised by non linear nearest neighbour spin interac…
New universality class for the three-dimensional XY model with correlated impurities: Application to He in aerogels
Carlos Vásquez-Romero, R. Paredes-Villegas, A. Hasmy +1
Encouraged by experiments on He in aerogels, we confine planar spins in the pores of simulated aerogels (diffusion limited cluster-cluster aggregation) in order to study the ef…
Evidence for a topological transition in nematic-to-isotropic phase transition in two dimensions
A. I. Farinas Sanchez, R. Paredes V., B. Berche
The nematic-to-isotropic orientational phase transition, or equivalently the model, is considered in two dimensions and the question of the nature of the phase transition is…
