XXZ自旋链中的谱对偶与五维规范理论

Spectral dualities in XXZ spin chains and five dimensional gauge theories

A. Mironov, A. Morozov, B. Runov, Y. Zenkevich, A. Zotov

摘要:

受超对称规范理论研究的最新进展的启发,我们提出了一个非常紧凑的XXZ自旋链之间的谱对偶公式。量子对偶性的作用由谱参量的傅里叶变换给出。我们调查的对偶在各种限制,特别是,证明它为q->1,即当它减少到XXX/Gaudin对偶。我们还证明了泛差算子是由经典谱曲线的正规序给出的。

英文摘要:

Motivated by recent progress in the study of supersymmetric gauge theories we propose a very compact formulation of spectral duality between XXZ spin chains. The action of the quantum duality is given by the Fourier transform in the spectral parameter. We investigate the duality in various limits and, in particular, prove it for q-->1, i.e. when it reduces to the XXX/Gaudin duality. We also show that the universal difference operators are given by the normal ordering of the classical spectral curves.
