一个自由的N = 2超对称系统:新的对称性

A Free N = 2 Supersymmetric System: Novel Symmetries

S. Krishna, R. P. Malik

摘要:

我们讨论了一组新的离散对称性的自由N = 2超对称(SUSY)量子力学系统,这是一个广泛研究的相互作用的SUSY模型的限制情况下的带电粒子被约束到一个球的狄拉克磁粒子的背景下移动。这个模型通常的连续对称性提供了微分几何的de Rham上同调算子的物理实现。新的离散对称与通常的连续对称之间的相互作用导致微分几何的(上)外导数之间的关系的物理实现。我们还利用超变量方法导出了该理论的幂零N = 2超对称性,并给出了幂零性质的几何起源和解释。最终,我们目前的研究(基于先天对称性)证明,我们的自由N = 2超对称性的例子是一个易于处理的模型霍奇理论。

英文摘要:

We discuss a set of novel discrete symmetries of a free N = 2 supersymmetric (SUSY) quantum mechanical system which is the limiting case of a widely-studied interacting SUSY model of a charged particle constrained to move on a sphere in the background of a Dirac magnetic monopole. The usual continuous symmetries of this model provide the physical realization of the de Rham cohomological operators of differential geometry. The interplay between the novel discrete symmetries and usual continuous symmetries leads to the physical realization of relationship between the (co-)exterior derivatives of differential geometry. We have also exploited the supervariable approach to derive the nilpotent N = 2 SUSY symmetries of the theory and provided the geometrical origin and interpretation for the nilpotency property. Ultimately, our present study (based on innate symmetries) proves that our free N = 2 SUSY example is a tractable model for the Hodge theory.
