摘要:

我们研究了一个具有二次哈密顿量的稀释平均场自旋玻璃模型。我们的主要结果利用一族随机变量的积分确立了极限自由能,这些随机变量是系统中自旋在边连通度变化时的淬火方差的弱极限。我们论证中的关键部分在于将这些随机变量识别为一个递归分布方程的唯一解。我们的结果尤其提供了稀释 Shcherbina-Tirozzi 模型的首个例子,其极限自由能可在任意逆温度和外场下导出。

英文摘要:

We study a diluted mean-field spin glass model with a quadratic Hamiltonian. Our main result establishes the limiting free energy in terms of an integral of a family of random variables that are the weak limits of the quenched variances of the spins in the system with varying edge connectivity. The key ingredient in our argument is played by the identification of these random variables as the unique solution to a recursive distributional equation. Our results in particular provide the first example of the diluted Shcherbina-Tirozzi model, whose limiting free energy can be derived at any inverse temperature and external field.
