Potts models with competing interactions
The mock A N N N I model is generalised in replacing the Ising spins by q-state Potts variables. Performing exact dedecoration transformations for general q and using Monte Carlo techniques in two dimensions for q = 3, a multitude of distinct spatially modulated long-range ordered phases, as well as phases with algebraic order, are found 10 spring from a multiphase point.
متن کاملGeneralized phase behavior of cluster formation in colloidal dispersions with competing interactions.
Colloidal liquids interacting with short range attraction and long range repulsion, such as proposed for some protein solutions, have been found to exhibit novel states consisting of equilibrium particle clusters. Monte Carlo simulations are performed for two physically meaningful inter-particle potentials across a broad range of interaction parameters, temperatures and volume fractions to loca...
متن کاملPhase behavior of a fluid with competing attractive and repulsive interactions.
Fluids in which the interparticle potential has a hard core, is attractive at moderate separations, and repulsive at large separations are known to exhibit unusual phase behavior, including stable inhomogeneous phases. Here we report a joint simulation and theoretical study of such a fluid, focusing on the relationship between the liquid-vapor transition line and any new phases. The phase diagr...
متن کاملSelf-consistent solution of phase separation with competing interactions.
We present a solution of a modified time-dependent Ginzburg-Landau equation in the limit of in6nite order-parameter dimension N. The scalar (N = 1) model is believed to describe phase separation in chemically reactive binary mixtures, block copolymers, and other systems where competing short-range and long-range interactions give rise to steady-state, spatially periodic structures. We present e...
متن کاملPhase diagram of the Ising square lattice with competing interactions
We restudy the phase diagram of the 2D-Ising model with competing interactions J1 on nearest neighbour and J2 on next-nearest neighbour bonds via Monte-Carlo simulations. We present the finite temperature phase diagram and introduce computational methods which allow us to calculate transition temperatures close to the critical point at J2 = 0.5J1. Further on we investigate the character of the ...
