类Calogero模型的超Lax算子与局部Dunkl算子的等价性

Equivalence of the super Lax and local Dunkl operators for Calogero-like models

A. I. Neelov

摘要:

继Shastry和Sutherland之后,我在振子势中构造了Calogero模型的超Lax算子。这些算子可用于Calogero模型及其超对称版本的本征函数和运动积分的推导。它们允许以快速的方式推断涉及该模型的Lax矩阵的几个关系。证明了Calogero和Sutherland模型的超Lax算子可以用超荷和我们最近用M.约菲从Dunkl算子的性质出发,可以很容易地导出Calogero模型和Sutherland模型的Lax矩阵和Hamilton算子之间的几个重要关系。

英文摘要:

Following Shastry and Sutherland I construct the super Lax operators for the Calogero model in the oscillator potential. These operators can be used for the derivation of the eigenfunctions and integrals of motion of the Calogero model and its supersymmetric version. They allow to infer several relations involving the Lax matrices for this model in a fast way. It is shown that the super Lax operators for the Calogero and Sutherland models can be expressed in terms of the supercharges and so called local Dunkl operators constructed in our recent paper with M. Ioffe. Several important relations involving Lax matrices and Hamiltonians of the Calogero and Sutherland models are easily derived from the properties of Dunkl operators.
