高斯自旋玻璃的可解平均场模型
A Solvable Mean Field Model of a Gaussian Spin Glass
摘要:
我们引入了一个具有高斯分布自旋和成对相互作用的平均场自旋玻璃模型,其耦合也是从正态高斯分布中随机抽取的。我们在整个相空间中完全控制了模型的主要物理性质(自由能、相图、涨落理论)。特别地,我们证明了在热力学极限下,自由能等于它的副本对称表达式。
英文摘要:
We introduce a mean field spin glass model with gaussian distribuited spins and pairwise interactions, whose couplings are drawn randomly from a normal gaussian distribution too. We completely control the main thermodynamical properties of the model (free energy, phase diagram, fluctuations theory) in the whole phase space. In particular we prove that in thermodynamic limit the free energy equals its replica symmetric expression.
