“…AdS 3 vacua also commonly appear in duals to compactifications of CFT 4 on Riemann surfaces [2][3][4][5][6][7][8][9], a topic of rekindled interest in recent years with improved understanding of compactifications on surfaces of non-constant curvature such as spindles. Some other venues in which AdS 3 vacua have played a prominent role JHEP08(2023)024 are geometric duals to c-extremisation [10,11] and dual descriptions of surface defects in higher dimensional CFTs [12][13][14][15][16].…”

We consider $$ \mathcal{N} $$ N = (n, 0) supersymmetric AdS3 vacua of type II supergravity realising the superconformal algebra $$ \mathfrak{osp} $$ osp (n|2) for n > 4. For the cases n = 6 and n = 5, one can realise these algebras on backgrounds that decompose as foliations of AdS3 × ℂℙ3 ( squashed ℂℙ3 for n = 5) over an interval. We classify such solutions with bi-spinor techniques and find the local form of each of them: they only exist in (massive) IIA and are defined locally in terms of an order 3 polynomial h similar to the AdS7 vacua of (massive) IIA. Many distinct local solutions exist for different tunings of h that give rise to bounded (or semi infinite) intervals bounded by physical behaviour. We show that it is possible to glue these local solutions together by placing D8 branes in the interior of the interval without breaking supersymmetry, which expands the possibilities for global solutions immensely. We illustrate this point with some simple examples. Finally we also show that AdS3 vacua for n = 7, 8 only exist in d = 11 supergravity and are all locally AdS4×S7.

We study the class of AdS3 × ℂℙ3 solutions to massive Type IIA supergravity with $$ \mathfrak{osp} $$ osp (6|2) superconformal algebra recently constructed in [1]. These solutions are foliations over an interval preserving $$ \mathcal{N} $$ N = (0, 6) supersymmetry in two dimensions, that in the massless limit can be mapped to the AdS4 × ℂℙ3 solution of ABJM/ABJ. We show that in the massive case extra NS5-D8 branes, that we interpret as $$ \frac{1}{2} $$ 1 2 -BPS surface defect branes within the ABJ theory, backreact in the geometry and turn one of the 3d field theory directions onto an energy scale, generating a flow towards a 2d CFT. We construct explicit quiver field theories that we propose flow in the IR to the (0, 6) SCFTs dual to the solutions. Finally, we show that the AdS3 solutions realise geometrically, in terms of large gauge transformations, an extension to the massive case of Seiberg duality in ABJ theories proposed in the literature.

Multiparametric families of nonsupersymmetric EAdS4 flows as well as asymptotically EAdS4 solitons and wormholes are constructed within the four-dimensional SO(8) gauged supergravity that describes the compactification of M-theory on S7. More concretely, the solutions are found within the so-called STU model that describes the U(1)4 invariant sector of the theory. The on-shell action and gravitational free energy are computed for the regular solutions, the latter being zero for the wormholes irrespective of supersymmetry. There are special loci in parameter space yielding solutions with enhanced (super)symmetry. Examples include a supersymmetric EAdS4 flow with SO(4)×SO(4) symmetry dual to a specific real mass deformation of ABJM on S3 as well as a nonsupersymmetric wormhole with SU(3)×U(1)2 symmetry. Uplift formulas for these and other examples to Euclidean solutions of 11-dimensional supergravity are presented and their complex nature discussed. Published by the American Physical Society 2024
