Abstract

A Monte Carlo simulation is used to investigate the two-dimensional spin-1 Ising antiferromagnet in the presence of an external magnetic field and a single-ion potential. Comparison is made between the results of this simulation and previous mean-field calculations. The phase diagram and the critical behavior of the model are discussed. In contrast to the mean-field picture, no decomposition of the tricritical point is observed.

Multicritical behavior of the antiferromagnetic spin-3/2 Blume-Capel model: Finite-size-scaling and Monte Carlo studies

Transfer-matrix finite-size-scaling calculations and Monte Carlo simulations are used to investigate the two-dimensional spin-3/2 Ising antiferromagnet in the presence of an external magnetic field and a single-ion potential. Comparison is made between the results of this study and previous mean-field calculations. The phase diagrams and the critical behavior of the model are discussed. In contrast to the mean-field picture, no decomposition of the tricritical point is observed.

Phase diagram for the antiferromagnetic Blume-Capel model near tricriticality

J. D. Kimel, Per Arne Rikvold, Yung‐Li Wang

We study the two-dimensional, antiferromagnetic Blume-Capel model on a square lattice by numerical transfer-matrix and Monte Carlo finite-size scaling methods, in order to investigate whether the line of tricritical points in this model may be decomposed into lines of critical end points and double critical points, as predicted by mean-field theory and recent Monte Carlo simulations on a three-dimensional cubic lattice. Conclusive numerical evidence is obtained, indicating that such decomposition does u/Inot occur in this two-dimensional model. The nondecomposition is explained in terms of the large fluctuations in the two-dimensional nearest-neighbor model, and we speculate that the situation may be different in two-dimensional antiferromagnetic models with weak, ferromagnetic next-nearest-neighbor interactions.

Monte Carlo renormalization-group study of tricritical behavior in two dimensions

David Paul Landau, Robert H. Swendsen

Using a Monte Carlo renormalization-group (MCRG) method we study tricritical behavior in two very different two-dimensional spin models: the Blume-Capel ferromagnet and the next-nearest-neighbor Ising antiferromagnet. The MCRG method is used to locate accurately tricritical points independent of the convergence of eigenvalue estimates. Despite the different symmetries and the different renormalization transformations used for the two models, in both cases we find four relevant tricritical eigenvalues which are essentially identical for both models. For the antiferromagnet, there is no indication of any decomposition of the tricritical point as predicted by mean-field theory, for ratios of intrasublattice to intersublattice coupling as small as (1/8).

Critical behavior of the spin- 3 2 Blume-Capel model in two dimensions

J. C. Xavier, Francisco Castilho Alcaraz, D. Peña Lara +1 more

The phase diagram of the spin-$\frac{3}{2}$ Blume-Capel model in two dimensions is explored by conventional finite-size scaling, conformal invariance, and Monte Carlo simulations. The model in its $\ensuremath{\tau}$-continuum Hamiltonian version is also considered and compared with other spin-$\frac{3}{2}$ quantum chains. Our results indicate that, different from the standard spin-1 Blume-Capel model, there is no multicritical point along the order-disorder transition line. This is in qualitative agreement with mean-field prediction, but in disagreement with previous approximate renormalization-group calculations.

Phase diagram and transition properties of the Blume-Capel model: A Monte Carlo study

Tenglong Li, Zhigang Feng, Jie Zhang

The Jx-Jy Blume-Capel model, with and without an external magnetic field, is investigated using the Monte Carlo method. Our aim is to verify the location of the tricritical point, examine the existence of reentrant behavior, and study the magnetocaloric properties of this specifically designed system. In the non-field case, the critical temperature given by the Monte Carlo simulations is lower compared to the conventional antiferromagnetic square lattice. When an external magnetic field is applied, we observed signs of a one-dimensional spontaneous symmetry-breaking phase in the mixed-states regime, which is counterintuitive with secondary specific-heat peak. We take the snapshot of this state and elucidated the underlying mechanisms using mean field theory in the field of spin-1 spinor Bose-Einstein condensate . Regarding reentrant behavior, we confirmed its occurrence as the magnetic field varies, but only when the temperature is kept constant. Temperature-dependent reentrant behavior could not be identified within this system. Finally, we examined the magnetocaloric properties and found no evidence of first-order phase transitions within the region of the considered phase-transition point. Although both inverse and direct magnetocaloric effects are present and related to the mixed state, we identified that the relevant phase transitions are all of the second order.

Phase Diagram of the Antiferromagnetic Blume-Capel Model on Triangular Lattice

Sojeong Park, Wooseop Kwak

We perform Monte-Carlo simulations of the anti-ferromagnetic (AF) spin-1 Blume- Capel (BC) model and the AF Ising model on triangular lattice. We estimate the exact critical magnetic fields for both models at zero temperature using the Wang-Landau sampling method. We also show the phase diagrams and the critical lines for the models using the joint density functions. We find that the shapes of critical lines for the models are identical, but the phase transitions across the critical lines are different.
