Zero-temperature phase transitions of an antiferromagnetic Ising model of general spin on a triangular lattice
We map the ground-state ensemble of antiferromagnetic Ising model of spin-S on a triangular lattice to an interface model whose entropic fluctuations are proposed to be described by an effective Gaussian free energy, which enables us to calculate the critical exponents of various operators in terms of the stiffness constant of the interface. Monte Carlo simulations for the ground-state ensemble...
متن کاملCorrelation Functions of the Ising Model with Multisite Interaction on the Husimi Lattice
We consider a general spin-1/2 Ising model with multisite interaction on the Husimi lattice with the coordination number q and derive an analytical expression of correlation functions for stable fixed points of the corresponding recurrence relation. We show that for q = 2 our model transforms to the two-state vertex model on the Bethe lattice with q = 3 and for the case q = 3, with only nearest...
متن کاملMagnetic Properties and Phase Transitions in a Spin-1 Random Transverse Ising Model on Simple Cubic Lattice
Within the effective-field theory with correlations (EFT), a transverse random field spin-1 Ising model on the simple cubic (z=6) lattice is studied. The phase diagrams, the behavior of critical points, transverse magnetization, internal energy, magnetic specific heat are obtained numerically and discussed for different values of p the concentration of the random transverse field.
متن کاملAn Ising Spin-S Model on Generalized Recursive Lattice
The Ising spin S model on recursive p polygonal structures in the external magnetic field is considered and the general form of the free energy and magnetization for arbitrary spin is derived. The exact relation between the free energies on infinite entire tree and on its infinite ”interior” is obtained. e-mail: [email protected] e-mail: [email protected] Permanent address: Ye...
متن کاملOrder by disorder in the antiferromagnetic Ising model on an elastic triangular lattice.
Geometrically frustrated materials have a ground-state degeneracy that may be lifted by subtle effects, such as higher-order interactions causing small energetic preferences for ordered structures. Alternatively, ordering may result from entropic differences between configurations in an effect termed order by disorder. Motivated by recent experiments in a frustrated colloidal system in which or...
