Ising链的单自旋翻转动力学

Single-spin-flip dynamics of the Ising chain

C. Godreche, J. -M. Luck

摘要:

我们考虑了具有最近邻影响和自旋反转对称性的铁磁伊辛链的最一般的单自旋翻转动力学。该动力学是Glauber动力学的两参数扩展,分别对应于非线性和不可逆性。相关的定态测度由链的铁磁哈密顿量的通常Boltzmann-Gibbs分布给出。我们研究这种动力学的性质,在无限和有限的温度下,在其参数空间,特别强调特殊的线和点。

英文摘要:

We consider the most general single-spin-flip dynamics for the ferromagnetic Ising chain with nearest-neighbour influence and spin reversal symmetry. This dynamics is a two-parameter extension of Glauber dynamics corresponding respectively to non-linearity and irreversibility. The associated stationary state measure is given by the usual Boltzmann-Gibbs distribution for the ferromagnetic Hamiltonian of the chain. We study the properties of this dynamics both at infinite and at finite temperature, all over its parameter space, with particular emphasis on special lines and points.
