Classical dimer model with anisotropic interactions on the square lattice
Hiromi Otsuka
We discuss phase transitions and the phase diagram of a classical dimer model with anisotropic interactions defined on a square lattice. For the attractive region, the perturbation…
Finite-size-scaling ansatz for the helicity modulus of the triangular-lattice three-spin interaction model
Hiromi Otsuka
The Berezinskii-Kosterlitz-Thouless-type continuous phase transition observed in the three-spin interaction model is discussed. The relevant field theory describes the topological…
Critical intermediate phase and phase transitions in a triangular-lattice three-spin interaction model: Level-spectroscopy approach
Hiromi Otsuka, Kiyohide Nomura
We investigate infinite-order phase transitions like the Berezinskii-Kosterlitz-Thouless transition observed in a triangular-lattice three-spin interaction model. Based on a field…
Effective Field Theory of Triangular-Lattice Three-Spin Interaction Model
Hiromi Otsuka
We discuss an effective field theory of a triangular-lattice three-spin interaction model defined by the variables. Based on the symmetry properties and the ideal-s…
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…
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…
