Using Monte Carlo simulation, we analyze phase transitions of two antiferromagnetic (AFM) triangular Blume-Capel (BC) models with AFM interactions between third-nearest neighbors. One model has hard-core exclusions between the nearest-neighbor (1NN) particles (3NN1 model) and the other has them between the nearest-neighbor and next-nearest-neighbor particles (3NN12 model). Finite-size scaling analysis reveals that in these models, the transition from the paramagnetic to long-range order (LRO… 
Random crystal field effects on antiferromagnetic spin-1 Blume–Capel model
The outcome of the random crystal field effects on the antiferromagnetic spin-1 Blume–Capel model and external magnetic field are examined on the Bethe Lattice in terms of exact recursion relations.
Effect of lattice coarsening and exclusion on phase-transition properties of the Bell–Lavis model
The temperature and order of the phase transition are studied for a less-coarsened Bell–Lavis model and the critical exponents obtained for the lower phase transition demonstrate the values typical for the three-state Potts model universality class.
Thermal algebraic-decay charge liquid driven by competing short-range Coulomb repulsion
We explore the possibility of a Berezinskii-Kosterlitz-Thouless-like critical phase for the charge degrees of freedom in the intermediate-temperature regime between the charge-ordered and disordered
Triangular Ising Ferromagnet with Mixed Spins (A = 1/2, B = 1/2, C = 1): Dynamic Magnetic Properties and Hysteresis Curves
The dynamic properties of the triangular Ising ferromagnet consisting of the mixed spins A = 1/2, B = 1/2, and C = 1 is studied by using the mean-field theory (MFT) as well as Glauber-type stochastic
Tensor renormalization group study of hard-disk models on a triangular lattice.
The TRG method demonstrates good convergence and turns out to be superior over TM with regard to considered models and shows the first-order phase transition in 3NN and 5NN models.
The Kinetic Spin-1 Ising System on Triangular Lattice: the Effects of Crystal Field and Frequency of Oscillating External Magnetic Field
Dynamic magnetic properties of the kinetic spin-1 Ising system on a triangular lattice are investigated by utilizing the mean field theory based on Glauber-type stochastic dynamics. In particular, we
