三维N=2超引力及其Godel超对称背景

N=2 supergravity in three dimensions and its Godel supersymmetric background

Maximo Banados, Alberto T. Faraggi, Stefan Theisen

摘要:

四维哥德尔时空的结构是M_3 × R。三维因子M_3是耦合到Maxwell-Chern-Simons理论的三维引力的精确解。我们在本文中建立了一个N=2的超引力扩展这个行动,并证明了哥德尔背景保持一半的所有超对称性。

英文摘要:

The four dimensional Godel spacetime is known to have the structure M_3 x R. It is also known that the three-dimensional factor M_3 is an exact solution of three-dimensional gravity coupled to a Maxwell-Chern-Simons theory. We build in this paper a N=2 supergravity extension for this action and prove that the Godel background preserves half of all supersymmetries.
