无细致平衡条件下一维伊辛模型的动力学

Dynamics of the One-Dimensional Ising Model without Detailed Balance Condition

Yuji Sakai, Koji Hukushima

摘要:

研究了一维伊辛模型基于斜细致平衡条件的不可逆马尔可夫链蒙特卡罗方法。为了理解这种方法的性质,对磁化强度的动态行为进行了分析。结果发现,与满足细致平衡条件的跃迁几率相比,满足倾斜细致平衡条件的跃迁几率可以减少磁化强度的弛豫时间,并且其中一个跃迁几率即使在局部自旋更新的情况下也会改变动力学临界指数.

英文摘要:

We study an irreversible Markov chain Monte Carlo method based on a skew detailed balance condition for an one-dimensional Ising model. Dynamical behavior of the magnetization density is analyzed in order to understand the properties of this method. As a result, it is found theoretically that the relaxation time of the magnetization density is reduced by using some transition probabilities satisfying the skew detailed balance condition, in comparison to that with the corresponding transition probability with the detailed balance condition, and that one of the transition probabilities changes the dynamical critical exponent even with a local spin update.
