非平移不变格点自旋系统的相关渐近性

Correlation asymptotics for non-translation invariant lattice spin systems

Oliver Matte

摘要:

利用半经典和微局部分析的方法,我们得到了某些非平移不变转移矩阵的格林核的渐近表达式。结合Bach和Møller的结果,给出了某些实值自旋的非平移不变晶格模型的截断两点关联函数的渐近公式。

英文摘要:

We obtain asymptotic expressions for the Green kernels of certain non-translation invariant transition matrices using methods of semiclassical and microlocal analysis. Combined with a result by Bach and Møller this yields asymptotic formulas for the truncated two-point correlation functions of certain non-translation invariant lattice models of real-valued spins.
