具体内容
稿件研究零场Sherrington–Kirkpatrick模型在逆温度β=1时的平稳自旋自相关。摘要表示,作者证明对高斯耦合与Rademacher耦合,该自相关具有共同的泛函标度极限:每个格点配速率一的热浴时钟,时间按n^{2/3}缩放,平均自旋自相关乘以n^{1/3},函数在紧正时间区间上依分布一致收敛。作者声称极限律不是点质量,保留样本间随机性,且函数在大时间趋于零。该结果属于平均场自旋玻璃动力学研究;当前收录摘要未给出证明细节。

英文原始摘要
We prove that the stationary spin autocorrelation of the zero-field Sherrington–Kirkpatrick model at inverse temperature β = 1 has a common functional scaling limit for Gaussian and Rademacher couplings. With rate-one heat-bath clocks at every site, time is scaled by n2/3 and the mean spin autocorrelation is multiplied by n1/3. The functions converge in law uniformly on compact positive-time intervals. Their limiting law is not a point mass: it retains sample-to-sample randomness, and its functions decay to zero at large times.
