摘要:
本文研究了奇长周期链上的一种特殊的各向异性XYZ模型,并推测了该模型的基态本征矢的某些分量的精确表达式。结果写在τ函数与皮卡德的椭圆解的Painlevé VI方程。与八顶点模型有关的其他问题的连接进行了简要讨论。
英文摘要:
We study a special anisotropic XYZ-model on a periodic chain of an odd length and conjecture exact expressions for certain components of the ground state eigenvectors. The results are written in terms of tau-functions associated with Picard's elliptic solutions of the Painlevé VI equation. Connections with other problems related to the eight-vertex model are briefly discussed.
