可积模型状态向量标量积的组合解释

Combinatorial Interpretation of the Scalar Products of State Vectors of Integrable Models

N. M. Bogoliubov, C. Malyshev

摘要:

通过Schur函数表示某些可积模型的Bethe波函数,可以将成熟的对称函数理论应用于热关联函数的计算。在计算标积和关联函数时所产生的代数关系是基于Schur函数的Binet-Cauchy公式。我们提供了一个组合的解释公式的标量产品的贝特状态向量的巢的自避免晶格路径构成所谓的西瓜配置。所提出的解释,反过来,与枚举的盒装平面分区。

英文摘要:

The representation of the Bethe wave functions of certain integrable models via the Schur functions allows to apply the well-developed theory of the symmetric functions to the calculation of the thermal correlation functions. The algebraic relations arising in the calculation of the scalar products and the correlation functions are based on the Binet-Cauchy formula for the Schur functions. We provide a combinatorial interpretation of the formula for the scalar products of the Bethe state-vectors in terms of nests of the self-avoiding lattice paths constituting the so-called watermelon configurations. The interpretation proposed is, in its turn, related to the enumeration of the boxed plane partitions.
