Sherrington-Kirkpatrick模型中时间尺度的分布

Distribution of time scales in the Sherrington-Kirkpatrick model

Alain Billoire

摘要:

通过动态蒙特卡罗模拟,得到了系统尺寸$N$和温度$T$不同时,Sherrington-Kirkpatrick模型平衡弛豫时间概率分布的数值数据.适当的照顾,热波动的弛豫时间估计是完全可以忽略不计相比,无序引起的波动。$\lnτ-\overline{\lnτ}$的概率分布与标度变量$N^{1/3} (T_c-T)$成比例,加强了$\overline{\lnτ}\propto N^{1/3}$在整个自旋玻璃相中的信念。

英文摘要:

Numerical data on the probability distribution of the equilibrium relaxation time of the Sherrington-Kirkpatrick model are obtained by means of dynamical Monte Carlo simulation, for several values of the system size $N$ and temperature $T$. Proper care is taken that the thermal fluctuations on the relaxation time estimates are totally negligible compared to the disorder induced fluctuations. The probability distribution of $\lnτ-\overline{\lnτ}$ scales with the scaling variable $N^{1/3} (T_c-T)$ strengthening the belief that $\overline{\lnτ}\propto N^{1/3}$ in the whole spin glass phase.
