结果表明,在一定条件下, 具有非均匀耦合和局域磁场的三角形自旋晶格 场可以被描述为量子行走在图上的投影, 深度为2的有序汉明格式。对于某些参数值, 模型表现出完美的状态转移之间的两个高峰, 晶格在某些情况下也观察到部分复苏。的 二元Krawtchouk多项式的Tratnik型,形成 深度为2的有序汉明格式的特征值矩阵给出了 能量本征态和职业基础之间的重叠 向量。
It is shown that the hopping of a single excitation on certain triangular spin lattices with non-uniform couplings and local magnetic fields can be described as the projections of quantum walks on graphs of the ordered Hamming scheme of depth 2. For some values of the parameters the models exhibit perfect state transfer between two summits of the lattice. Fractional revival is also observed in some instances. The bivariate Krawtchouk polynomials of the Tratnik type that form the eigenvalue matrices of the ordered Hamming scheme of depth 2 give the overlaps between the energy eigenstates and the occupational basis vectors.
