自旋梯上Kitaev模型谱的完全刻画

A complete characterization of the spectrum of the Kitaev model on spin ladders

Vahid Karimipour

摘要:

我们研究了梯形网络上的Kitaev模型,得到了封闭形式的哈密顿量的完整谱。封闭的和可管理的形式的所有特征值和特征向量,使我们能够计算的配分函数和平均值的非本地运营商除了约化密度矩阵的不同子系统在任意温度下。它也简要地讨论了如何将这些考虑可以推广到更一般的晶格,包括三脚梯子和二维正方形晶格。

英文摘要:

We study the Kitaev model on a ladder network and find the complete spectrum of the Hamiltonian in closed form. Closed and manageable forms for all eigenvalues and eigenvectors, allow us to calculate the partition function and averages of non-local operators in addition to the reduced density matrices of different subsystems at arbitrary temperatures. It is also briefly discussed how these considerations can be generalized to more general lattices, including three-leg ladders and two dimensional square lattices.
