零温附近Edwards-Anderson模型中不存在复本对称性破缺

Absence of replica symmetry breaking in the Edwards-Anderson model near zero temperature

C. Itoi, H. Shimajiri, Y. Sakamoto

摘要:

证明了在Edwards-Anderson模型中,对于几乎所有的连续随机交换相互作用,基态都是唯一的,任何重叠小于其最大值的激发态都具有大于2维的大能量,概率为1.由于自旋重叠被证明是集中在其最大值在基态,复本对称性破缺不会发生在爱德华-安德森模型接近零温度。

英文摘要:

It is proven that the ground state is unique in the Edwards-Anderson model for almost all continuous random exchange interactions, and any excited state with the overlap less than its maximal value has large energy in dimensions higher than two with probability one. Since the spin overlap is shown to be concentrated at its maximal value in the ground state, replica symmetry breaking does not occur in the Edwards-Anderson model near zero temperature.
