Title: Normalized entropy density of the 3D 3-state Potts model

Abstract

Using a multicanonical Metropolis algorithm we have performed Monte Carlo simulations of the 3D 3-state Potts model on L{sup 3} lattices with L=20, 30, 40, 50. Covering a range of inverse temperatures from {beta}{sub min}=0 to {beta}{sub max}=0.33 we calculated the infinite volume limit of the entropy density s({beta}) with its normalization obtained from s(0)=ln3. At the transition temperature the entropy and energy endpoints in the ordered and disordered phase are estimated employing a novel reweighting procedure. We also evaluate the transition temperature and the order-disorder interface tension. The latter estimate increases when capillary waves are taken into account.

  • In studies of the QCD deconfining phase transition or crossover by means of heavy ion experiments, one ought to be concerned about nonequilibrium effects due to heating and cooling of the system. In this paper we extend our previous study of Glauber dynamics of 2D Potts models to the 3D 3-state Potts model, which serves as an effective model for some QCD properties. We investigate the linear theory of spinodal decomposition in some detail. It describes the early time evolution of the 3D model under a quench from the disordered into the ordered phase well, but fails in 2D. Further,more » the quench leads to competing vacuum domains, which are difficult to equilibrate, even in the presence of a small external magnetic field. From our hysteresis study we find, as before, a dynamics dominated by spinodal decomposition. There is evidence that some effects survive in the case of a crossover. But the infinite volume extrapolation is difficult to control, even with lattices as large as 120{sup 3}.« less
  • An importance-sampling Monte Carlo method is applied to the calculation of [Gamma](E), the number of states for a given energy E, and [Gamma](E,S), the number of states for given energy E and spin S, of antiferromagnetic two-dimensional q = 2,3,4,5,6 Potts models. In this paper, the entropy function is derived for various temperatures, and the authors' results for the 1 = 3 model show a continuous phase transition.
  • Traditional definition of phase transition involves an infinitely large system in thermodynamic limit. Finite systems such as biological proteins exhibit cooperative behavior similar to phase transitions. We employ recently discovered analysis of inflection points of microcanonical entropy to estimate the transition temperature of the phase transition in q state Potts model on a finite two dimensional square lattice for q=3 (second order) and q=8 (first order). The difference of energy density of states (DOS) Δ ln g(E) = ln g(E+ ΔE) −ln g(E) exhibits a point of inflexion at a value corresponding to inverse transition temperature. This feature is commonmore » to systems exhibiting both first as well as second order transitions. While the difference of DOS registers a monotonic variation around the point of inflexion for systems exhibiting second order transition, it has an S-shape with a minimum and maximum around the point of inflexion for the case of first order transition.« less
  • Some nontrivial integrals of motion for the scaling 3-state Potts model constructed explicitly. These integrals of motion prove the corresponding scattering matrix to be factorizable and allow one to derive this S-matrix under a few natural assumptions.
  • The 3-state Potts model with chemical potential is mapped to a flux representation where the complex action problem is resolved. We perform a Monte Carlo simulation based on a worm algorithm to study the phase diagram of the model. Our results shed light on the role which center symmetry and its breaking play for the QCD phase diagram.
