AdS2 × S2 × CY2 solutions in Type IIB with 8 supersymmetries

A bstract We present a new infinite family of Type IIB supergravity solutions preserving eight supercharges. The structure the space is AdS 2 × S CY 1 fibered over an interval. These can be related through double analytical continuations with those recently constructed in [1]. Both types are however dual to very different superconformal quantum mechanics. show that our fit locally class 2d Riemann surface ? by Chiodaroli, Gutperle and Krym, absence D3 D7 brane sources. compare global D’Hoker for annulus. also construct cohomogeneity-two using non-Abelian T-duality. Finally, we relate holographic central charge one dimensional system combination electric magnetic fluxes. propose extremisation principle from functional out RR
