Dipole deformed background — holography and string spectrum

Holography on dipole deformed background is an interesting topic for many reasons. On the one hand, the background is deformed, and therefore is a simple example of non-AdS holography. On the other hand, the bulk spacetime can be obtained by a TsT transformation, and therefore many properties are inherited from AdS. Furthermore, dipole deformed background is closely related to Kerr/CFT correspondence. By studying dipole theory, we could learn some information about the CFT that is dual to Kerr. In this talk I will first talk about dipole/CFT dual from the asymptotic symmetry group analysis, and then from string sigma models.
