چکیده

We point out that the claim of strong universality of [1] is incorrect, as it contradicts known rigorous results. AMS 2000 subject classification: 82B20, 82B26, 60K35.

بررسی گذار فازهای شبکه دوبعدی کگومی در مدل XY ناهمسانگرد و با استفاده از روش میدان میانگین

 In this work we investigated the critical properties of the anti-ferromagnetic XY model on a two dimensional Kagome lattice under single-ion easy-axes anisotropy. Employing the mean field theory, we found that this model shows a second order phase transition from disordered to all-in all-out state for any value of anisotropy.

0 D ec 1 99 6 Phase diagram of the restricted solid - on - solid model coupled to the Ising model

We study the phase transitions of a restricted solid-on-solid model coupled to an Ising model, which can be derived from the coupled XY-Ising model. There are two kinds of phase transition lines. One is a Ising transition line and the other is surface roughening transition line. The latter is a KT transition line from the viewpoint of the XY model. Using a microcanonical Monte Carlo technique, ...

Coulomb Gas Formulation of Two Dimensional Kosterlitz-Thouless Phase Transition

The absence of conventional long range order in the classical two dimensional xy model is introduced. Two main types of excitations of this model, spin wave and vortices, are analyzed in the framework of generalized theory of elasticity. The Hamiltonian is then mapping onto the two dimensional Coulomb gas model and then critical temperature of the Kosterlitz-Thouless transition is located by a ...

Thermoelastic Interaction in a Three-Dimensional Layered Sandwich Structure

The present article investigates the thermoelastic interaction in a three-dimensional homogeneous and isotropic sandwich structure using the dual-phase-lag (DPL) model of generalized thermoelasticity. The incorporated resulting non-dimensional coupled equations are applied to a specific problem in which a sandwich layer of unidentical homogeneous and isotropic substances is subjected to time-de...

The XY Model Coupled to Two-Dimensional Quantum Gravity

We perform Monte Carlo simulations using the Wolff cluster algorithm of the XY model on both fixed and dynamical phi-cubed graphs (i.e. without and with coupling to two-dimensional quantum gravity). We compare the numerical results with the theoretical expectation that the phase transition remains of KT type when the XY model is coupled to gravity. We also examine whether the universality we di...
