Abstract

Using computer-based simulation methods, phase transitions in the three-dimensional weakly diluted Potts model with the spin state number q = 5 are studied. Systems with linear dimensions L × L × L = N, L = 10–40, at spin concentrations p = 1.00 and 0.90 are considered. The obtained numerical data indicate that introduction of a minor disorder in the form of nonmagnetic impurities (p = 0.90) into the three-dimensional Potts model with q = 5 is not significant for the first-order phase transition.

q = 5 的三维弱稀释 Potts 模型中的相变

摘要

使用基于计算机的模拟方法，研究了自旋态数q = 5的三维弱稀释 Potts 模型中的相变。考虑具有线性尺寸L × L × L  = N、L = 10–40、自旋浓度p = 1.00 和 0.90 的系统。获得的数值数据表明，在q = 5的三维 Potts 模型中引入非磁性杂质 ( p = 0.90) 形式的次要无序对于一级相变并不显着。
