自旋玻璃关联函数的单调性缺失

Lack of monotonicity in spin glass correlation functions

Pierluigi Contucci, Francesco Unguendoli, Cecilia Vernia

摘要:

我们研究了自旋玻璃系统的相互作用随机变量的重新标度的响应和数值研究的关联函数的行为相对于体积。而对于铁磁体,局域能量关联函数随尺度单调增加,因此,相对于系统的体积,我们发现,在一般的自旋玻璃模型中,这些单调性被破坏。

英文摘要:

We study the response of a spin glass system with respect to the rescaling of its interaction random variables and investigate numerically the behaviour of the correlation functions with respect to the volume. While for a ferromagnet the local energy correlation functions increase monotonically with the scale and, by consequence, with respect to the volume of the system we find that in a general spin glass model those monotonicities are violated.
