多数投票模型中的短时动力学:有序和无序初始情形

Short-time dynamic in the Majority vote model: The ordered and disordered initial cases

Francisco Sastre

摘要:

本文从有序态和无序态出发,对二维多数表决模型进行了短时蒙特卡罗模拟。已经发现,有两个伪临界点,每一个都在以前报道的值使用四阶累积量交叉方法进行的误差范围内。结果表明,该模型的短时动力学特性对初始条件具有依赖性。基于这种依赖关系,提出了一种计算该模型伪临界点和提取动态临界指数$z$和静态临界指数$β/ν$的方法。

英文摘要:

This work presents short-time Monte Carlo simulations for the two dimensional Majority-vote model starting from ordered and disordered states. It has been found that there are two pseudo-critical points, each one within the error-bar range of previous reported values performed using fourth order cumulant crossing method. The results show that the short-time dynamic for this model has a dependence on the initial conditions. Based on this dependence a method is proposed for the evaluation of the pseudo critical points and the extraction of the dynamical critical exponent $z$ and the static critical exponent $β/ν$ for this model.
