Zusammenfassung
Monte Carlo simulations are performed to study the two-dimensional Potts models with q = 3 and 4 states on directed small-world network. The
disordered system is simulated applying the heat bath Monte Carlo update
algorithm. The first-order and second-order phase transitions are found for q = 3 depending on the rewiring probability p, but for q = 4 the
system presents only a first-order phase transition for any value p.
This critical behavior is different from the Potts model on a square lattice, where the second-order phase transition is present for q <= 4
and a first-order phase transition is present for q > 4. (C) 2013
