THE STUDY OF QUENCHED BOND RANDOMNESS BY WANG–LANDAU ALGORITHM

摘要: Monte Carlo simulations using the recently proposed Wang–Landau algorithm are performed to q = 8 state Potts model in two dimension with various degrees of randomness. We systematically studied effect quenched bond randomness system which has first-order phase transition. All and measurements were done from pure case r 1 0.4. Physical quantities such as energy density ground-state entropy evaluated at all temperatures. have also obtained probability distributions monitor softening transitions. It appears quite feasible simulate spin systems by algorithm.
