摘要:
我们考虑了一类具有p-spin相互作用的自旋玻璃模型在横向磁场中的自由能。当p趋近于无穷大时,无限系统大小的自由能被证明收敛到量子随机能量模型的自由能。这通过结合现有的分析技术,处理此类量子玻璃的非交换性质,以及描述经典p-体玻璃中极端负偏差的典型几何特性来实现。我们还回顾了相应经典自由能的性质,并提出了关于量子情况中1/p修正的猜想。
英文摘要:
We consider the free energy of a class of spin glass models with $ p$-spin interactions in a transverse magnetic field. As $ p \to \infty $, the infinite system-size free energy is proven to converge to that of the quantum random energy model. This is accomplished by combining existing analytical techniques addressing the non-commutative properties of such quantum glasses, with the description of the typical geometry of extreme negative deviations of the classical $ p $-spin glass. We also review properties of the corresponding classical free energy and conjectures addressing $ 1/p $-corrections in the quantum case.
