论文摘要
提出了一个新的可解决的二维自旋晶格模型，该模型在定期的三角形形状上定义。站点之间的跳跃幅度与某些双变量双HAHN多项式的复发系数有关。对于参数的特定选择，显示出完美的状态转移和分数复兴。
A new solvable two-dimensional spin lattice model defined on a regular grid of triangular shape is proposed. The hopping amplitudes between sites are related to recurrence coefficients of certain bivariate dual-Hahn polynomials. For a specific choice of the parameters, perfect state transfer and fractional revival are shown to take place.
