摘要

一些研究利用中心自旋模型的可积结构来加深对这些基本系统的理解。近年来，发现了具有XX相互作用的系统的潜在超对称性。本文报道了一类具有XY相互作用的中心自旋模型也是超对称的和可积的。对于所有粒子都自旋为1/2的情况，给出了相关的Bethe Ansatz解。

Supersymmetry and integrability for a class of XY central spin models

Abstract Several studies have exploited the integrable structure of central spin models to deepen understanding of these fundamental systems. In recent years, an underlying supersymmetry for systems with XX interactions has been uncovered. Here we report that a class of central spin models with XY interactions is also supersymmetric and integrable. The associated Bethe Ansatz solution is presented for the case where all particles are spin-1/2.
