本文研究软球Sherrington-Kirkpatrick模型,证明其自由能在高温区呈高斯涨落,低温区由最大特征值主导并收敛于GOE Tracy-Widom分布,表明软径向约束保留经典模型的涨落转变。
AI 中文摘要
我们考虑软版本的球面Sherrington-Kirkpatrick模型,其中球面约束被径向限制项所替代。我们证明,在适当的谱假设下,对于实对称无序矩阵,自由能表现出两种不同的涨落机制。在高温区域,涨落渐近服从高斯分布。在低温区域,涨落由最大特征值控制,并收敛于GOE Tracy-Widom分布。这些结果表明,软径向约束保留了经典球面Sherrington-Kirkpatrick模型的涨落转变。
英文摘要
We consider a soft version of the spherical Sherrington-Kirkpatrick model, where the spherical constraint is replaced by a radial confinement term. We prove that, for a real symmetric disorder matrix under suitable spectral assumptions, the free energy exhibits two distinct fluctuation regimes. In the high-temperature regime, the fluctuations are asymptotically Gaussian. In the low-temperature regime, the fluctuations are governed by the largest eigenvalue and converge to the GOE Tracy-Widom distribution. These results show that the soft radial constraint preserves the fluctuation transition of the classical spherical Sherrington-Kirkpatrick model.
