超对称力学中的Nahm方程

Nahm equations in supersymmetric mechanics

Sergey Fedoruk, Evgeny Ivanov, Olaf Lechtenfeld

摘要:

我们详细阐述了一个新的模型N=4超对称力学与额外的自旋变量。动态线性(1,4,3)多重态耦合到“半动态”线性(3,4,1)多重态,代表Wess-Zumino作用量中的自旋自由度。这两个多重态的独特耦合将动力学玻色子变量与SU(2)三重态自旋变量的任意谐波函数联系起来。我们在经典和量子水平上证明,N=4的超对称性等价于自旋变量的Nahm方程,动力学玻色子作为演化参数。我们详细地处理的一个和两个双折射以及一些特殊的多折射配置。其中一个晶体表现出超共形OSp(4| 2)对称性,而对于多重组态,只有N=4,d=1的Poincare超对称性存在。

英文摘要:

We elaborate on a novel model of N=4 supersymmetric mechanics with extra spin variables. A dynamical linear (1,4,3) multiplet is coupled to a "semi-dynamical" linear (3,4,1) multiplet representing spin degrees of freedom in a Wess-Zumino action. The unique coupling of these two multiplets relates the dynamical bosonic variable to an arbitrary harmonic function of the SU(2) triplet of spin variables. As we prove at the classical and quantum level, N=4 supersymmetry is equivalent to the Nahm equations for the spin variables, with the dynamical boson as evolution parameter. We treat in detail the one- and two-monopole as well as some special multi-monopole configurations. While one monopole exhibits superconformal OSp(4|2) symmetry and was worked out previously, only N=4, d=1 Poincare supersymmetry survives for multi-monopole configurations.
