(超)史瓦西力学

(super)Schwarzian mechanics

Nikolay Kozyrev, Sergey Krivonos

摘要:

在本文中,我们重新使用非线性实现的超对称Schwarzians的建设。我们表明,${\cal N}=0,1,2,3,4$超对称Schwarzians可以系统地获得某些投影的Maurer-Cartan形式的超共形群后,对他们施加简单的条件。我们还提出了超对称Schwarzian作用量定义为积的Cartan形式的积分。与以前的尝试,以获得超Schwarzians内的非线性实现技术相比,我们的一组约束条件不施加任何限制的超Schwarzians。

英文摘要:

In this paper we revisit the construction of supersymmetric Schwarzians using nonlinear realizations. We show that ${\cal N}=0,1,2,3,4$ supersymmetric Schwarzians can be systematically obtained as certain projections of Maurer-Cartan forms of superconformal groups after imposing simple conditions on them. We also present the supersymmetric Schwarzian actions defined as the integrals of products of Cartan forms. In contrast with the previous attempts to obtain the super-Schwarzians within nonlinear realizations technique, our set of constraints does not impose any restriction on the super-Schwarzians.
