自旋玻璃随机稳定性的严格证明

Spin-Glass Stochastic Stability: a Rigorous Proof

P. Contucci, C. Giardina'

摘要:

我们证明了属性的随机稳定性先前引入的后果(未经证实)连续性假设的温度下的自旋玻璃淬火状态。我们发现,随机稳定性保持在β-平均的Sherrington-Kirkpatrick模型的重叠函数的平方和爱德华兹-安德森模型的键重叠。我们证明了在热力学极限下达到该性质的体积速率为V^{-1}。作为一个副产品,我们表明,随机稳定性的身份与Ghirlanda和Guerra的不同的方法时,仅适用于热波动。

英文摘要:

We prove the property of stochastic stability previously introduced as a consequence of the (unproved) continuity hypothesis in the temperature of the spin-glass quenched state. We show that stochastic stability holds in beta-average for both the Sherrington-Kirkpatrick model in terms of the square of the overlap function and for the Edwards-Anderson model in terms of the bond overlap. We show that the volume rate at which the property is reached in the thermodynamic limit is V^{-1}. As a byproduct we show that the stochastic stability identities coincide with those obtained with a different method by Ghirlanda and Guerra when applyed to the thermal fluctuations only.
