摘要

We construct AdS3 × Y7 solutions of type IIB supergravity, where Y7 is a smooth S5 bundle over a spindle Σ(nN, nS), which are dual to 𝒩 = (0, 2) SCFTs in d = 2. The solutions are constructed using the D = 5 STU U(1)3 gauged supergravity theory coupled to a hyperscalar charged under U(1)B. We investigate spindle solutions with two new features: first, we allow (nN, nS) to be non-coprime integers, including orbifolds of the round S2, which can lead to non-unique, inequivalent uplifts, distinguished by the hyperscalar spectra, for given magnetic flux through the spindle. Second, we also allow the hyperscalar to vanish at the poles leading to solutions carrying non-vanishing U(1)B flux. The new hyperscalar AdS3 solutions can naturally arise as the endpoint of RG flows, triggered by relevant hyperscalar deformations of the AdS3 solutions of the STU model.
