Computer simulation of critical behavior of two-dimensional weakly diluted antiferromagnetic Potts model on a triangular lattice

The critical behavior of a two-dimensional weakly diluted antiferromagnetic Potts model with spin states $q$ = 3 on a triangular lattice is computationally simulated. The systems with periodic boundary conditions were calculated, when spin concentrations $p$ were 1.0 and 0.9. Systems with linear dimensions $L\times L=N$ and $L$ = 9–144 were considered. Static critical exponents of heat capacity $\alpha$, the susceptibility $\gamma$, the order parameter $\beta$, and critical exponent $\nu$ for a correlation radius are calculated based on a theory of finite-dimensional scaling.
