Gaudin模型和KP层次的主T算子
The master T-operator for the Gaudin model and the KP hierarchy
摘要:
按照[arXiv:1112.3310]的方法,我们构造了具有扭曲边界条件的量子Gaudin模型的主T算子,并证明了它满足经典KP族的双线性恒等式和Hirota方程.我们还描述了一类的解决方案的KP的层次,对应于主T-运营商的特征值和研究动态的零点的谱参数的函数。这意味着量子Gaudin模型和经典Calogero-Moser质点系之间有着显著的联系。
英文摘要:
Following the approach of [arXiv:1112.3310], we construct the master T -operator for the quantum Gaudin model with twisted boundary conditions and show that it satisfies the bilinear identity and Hirota equations for the classical KP hierarchy. We also characterize the class of solutions to the KP hierarchy that correspond to eigenvalues of the master T-operator and study dynamics of their zeros as functions of the spectral parameter. This implies a remarkable connection between the quantum Gaudin model and the classical Calogero-Moser system of particles.
