Holography of class F field theories

Regular Seminar Morteza Hosseini (Kavli IPMU)

11:00 IC
room Zoom

I will perform a consistent reduction of 6d matter-coupled F(4) gauged supergravity on a compact Riemann surface of genus g, at the level of the bosonic fields. The result is an N=2 gauged supergravity coupled to two vector multiplets and a single hypermultiplet. The four-dimensional model is holographically dual to the 3d superconformal field theories of class F, describing different brane systems in massive type IIA and IIB wrapped on the Riemann Surface. I will then use the results to find the first examples of dyonic static black holes of class F and perform a microscopic counting of their entropy via the 5d topologically twisted index. I will also find new asymptotically AdS solutions, including rotating black holes, in the subtruncations of the 4d model, providing predictions for the squashed S^3 partition functions and the superconformal and refined twisted indices of class F field theories.
