IIB型超引力中AdS空间的约旦变形

A Jordanian deformation of AdS space in type IIB supergravity

Io Kawaguchi, Takuya Matsumoto, Kentaroh Yoshida

摘要:

我们考虑AdS_5xS^5超弦作用量的Jordan变形,取一个满足经典Yang-Baxter方程的简单R算子。在坐标系下,导出了度量形式和NS-NS两种形式。只有AdS部分被变形,得到的几何包含3D薛定谔时空作为子空间。然后,我们提出了完整的解决方案,在IIB型超引力通过确定其他领域的组成部分。特别地,在R-R三态场强作用下,该解的对称性为[SL(2,R)xU(1)^2] x [SU(3)xU(1)],并且具有各向异性尺度对称性.

英文摘要:

We consider a Jordanian deformation of the AdS_5xS^5 superstring action by taking a simple R-operator which satisfies the classical Yang-Baxter equation. The metric and NS-NS two-form are explicitly derived with a coordinate system. Only the AdS part is deformed and the resulting geometry contains the 3D Schrodinger spacetime as a subspace. Then we present the full solution in type IIB supergravity by determining the other field components. In particular, the dilaton is constant and a R-R three-form field strength is turned on. The symmetry of the solution is [SL(2,R)xU(1)^2] x [SU(3)xU(1)] and contains an anisotropic scale symmetry.
