Sachdev-Ye-Kitaev模型与自由Majorana变分态

The Sachdev-Ye-Kitaev model and free Majorana variational states

Daniel Ish, Mark Srednicki

摘要:

通过混合的分析和数值技术,我们探讨了最佳逼近的自由Majorana状态的Sachdev-Ye-Kitaev模型的个人disorder realizations,以及它的推广,我们阐明了已知的时间反演对称性破缺相的性质在广义模型,找到强有力的证据“自旋玻璃“秩序。对于Sachdev-Ye-Kitaev模型本身,我们的结果是不确定的,但表明在零温度下可能存在类似的顺序。

英文摘要:

Through a mixture of analytic and numerical techniques, we explore the optimal approximation by a free Majorana state to individual disorder realizations of the Sachdev-Ye-Kitaev model, along with a generalization of it. We elucidate the properties of the known time-reversal symmetry breaking phase in the generalized model, finding strong evidence of "spin glass" order. For the Sachdev-Ye-Kitaev model itself, our results are inconclusive but suggest a similar order may be present at zero temperature.
