Monte Carlo study of the antiferromagnetic three-state Potts model with staggered polarization field on the square lattice
Yutaka Okabe, Hiromi Otsuka
Using the Wang-Landau Monte Carlo method, we study the antiferromagnetic (AF) three-state Potts model with a staggered polarization field on the square lattice. We obtain two phase…
Multispin Coding Technique for Nonequilibrium Reweighting
Hwee Kuan Lee, Yutaka Okabe
We present the multispin coding for the nonequlibrium reweighting method of the Monte Carlo simulation, that was developed by the present authors. As an illustration, we treat the…
Exchange Bias with Interacting Random Anti-ferromagnetic Grains
Hwee Kuan Lee, Yutaka Okabe
A model consisting of random interacting anti-ferromagnetic (AF) grains coupled to a ferromagnetic (FM) layer is developed to study the exchange bias phenomenon. This simple model…
Global phase diagram and six-state clock universality behavior in the triangular antiferromagnetic Ising model with anisotropic next-nearest-neighbor coupling: Level-spectroscopy approach
Hiromi Otsuka, Yutaka Okabe, Kiyohide Nomura
We investigate the triangular-lattice antiferromagnetic Ising model with a spatially anisotropic next-nearest-neighbor ferromagnetic coupling, which was first discussed by Kitatani…
Mapping Monte Carlo to Langevin dynamics: A Fokker-Planck approach
X. Z. Cheng, M. B. A. Jalil, Hwee Kuan Lee +1
We propose a general method of using the Fokker-Planck equation (FPE) to link the Monte-Carlo (MC) and the Langevin micromagnetic schemes. We derive the drift and disusion FPE term…
