Abstract

We use holography and four-dimensional N=4\,\mathcal{N}=4\, gauged supergravity to collect evidence for a large class of interconnected three-dimensional N=2\,\mathcal{N}=2\, conformal field theories. On the gravity side, we construct a one-parameter family of ISO(3)×ISO(3)\,{\textrm{ISO}(3) \times \textrm{ISO}(3)} gaugings of half-maximal supergravity containing a rich structure of N=2\,\mathcal{N}=2\, AdS4_{4} solutions at fixed radius. By looking at excitations around these AdS4_{4} solutions, the spectrum of low lying operators in the dual N=2\,\mathcal{N}=2\, CFT3_{3}'s is computed and further arranged into osp(24)\,\mathfrak{osp}(2|4) supermultiplets. Upon suitable removal of gauge redundancies, we identify the Zamolodchikov metric on the conformal manifold dual to the AdS4_{4} moduli space, and recover previous results in the S-fold literature. Two special points of N=4\,\mathcal{N}=4\, supersymmetry enhancement occur. While one describes an S-fold CFT3_{3} dual to a non-geometric type IIB twisted compactification, the string-theoretic realisation of the other, if any, is still lacking.
