Abstract

The relaxation processes in an Ising spin glass are discussed in terms of random walks on a closed surface in phase space. Stretched exponential behaviour appears in a simple manner and the spin glass transition is identified with a percolation threshold in eigenstate space Les processus de relaxation dans un verre de spin Ising sont discutes en termes de la marche aleatoire sur une surface fermee dans l'espace des phases. Le comportement exponentiel etire est demontre de facon simple, et la transition verre de spin est associee au seuil de percolation dans l'espace des etats propres
闭环上的随机漫步和自旋玻璃弛豫
从相空间封闭表面上的随机漫步的角度讨论了伊辛自旋玻璃中的弛豫过程。拉伸指数行为以一种简单的方式出现,自旋玻璃跃迁与本征态空间中的渗透阈值相一致。整体性能指数证明了因素的简单性,而过渡曲线证明了因素的简单性,同时也证明了渗流和空间的适当性
