S-folds and holographic RG flows on the D3-brane
Adolfo Guarino, Colin Sterckx
Abstract
A bstract Type IIB S-folds of the form AdS 4 × S 1 × S 5 are conjectured to correspond to new strongly coupled three-dimensional CFT’s on a localised interface of SYM 4 . In this work we construct holographic RG flows on the D3-brane that generically connect anisotropic deformations of SYM 4 in the UV to various S-fold CFT’s in the IR with different amounts of supersymmetry and flavour symmetries. Examples of holographic RG flows between S-fold CFT’s are also presented. Lastly a geometric interpretation of axion deformations is provided in terms of monodromies on the internal S 5 when moving around the S 1 . Special attention is paid to the monodromy-induced patterns of symmetry breaking as classified by the mapping torus T h (S 5 ).
