压缩三球面上的可积超弦

Integrable Superstrings on the Squashed Three-sphere

Domenico Orlando, Linda I. Uruchurtu

摘要:

本文研究了AdS 3、压缩的三球和四环的直积(AdS 3 \times SqS 3 \times T4)上的II型超弦理论.我们推导出明确的Green-Schwarz作用,并详细讨论了隐藏的可积结构对应的本地和非本地电流。我们发现,该模型是经典可积的,电流产生一个完整的psu(1,1| 2)超代数,即使相应的时空等距被挤压破坏。

英文摘要:

In this note we study type II superstring theory on the direct product of AdS3, the squashed three-sphere and a four-torus (AdS3 \times SqS3 \times T4). We derive explicitly the Green-Schwarz action and discuss in detail the hidden integrable structure corresponding to local and non-local currents. We find that the model is classically integrable and that the currents generate a full psu(1, 1|2) superalgebra, even though the corresponding spacetime isometries are broken by the squashing.
