p=2自旋玻璃模型中的二级动力学跃迁

Second-order dynamic transition in a p=2 spin-glass model

Kristina Van Duijvendijk, Robert L. Jack, Frédéric Van Wijland

摘要:

考虑p=2的无序p自旋模型的动力学,在Ruelle的热力学形式下分析动力学,利用动力学活动的指示器构造相应的动力学Gibbs系综.我们证明,在低温(自旋玻璃)阶段的模型的动力学发生在动态活跃和不活跃的轨迹之间的二阶相变。我们还表明,在一个三维铁磁体的相关模型中发现了相同的行为。

英文摘要:

We consider the dynamics of a disordered p-spin model with p=2, analyzing the dynamics within Ruelle's thermodynamic formalism, We use an indicator of the dynamical activity to construct the relevant dynamical Gibbs ensemble. We prove that the dynamics in the low-temperature (spin glass) phase of the model take place at a second-order phase transition between dynamically active and inactive trajectories. We also show that the same behaviour is found in a related model of a three-dimensional ferromagnet.
