Spherical branes
No full textAbstract We construct new solutions of ten-dimensional supergravity with sixteen super-charges which describe the backreaction of Dp-branes with spherical worldvolume. These solutions are holographically dual to the (p + 1)-dimensional maximally supersymmetric Yang-Mills theory on S p+1. The finite size of the sphere provides an IR cut-off for the gauge theory which is manifested in the supergravity solution as a smooth cap-off of the geometry. In the UV the size of the sphere plays no role and the backgrounds asymptote to the well-known supergravity solutions that describe the near-horizon limit of flat Dp-branes. We compute the on-shell action of our spherical brane solutions and show that it is in agreement with recent supersymmetric localization results for the free energy of maximal SYM theory on S p+1
Spherical branes and the BMN matrix quantum mechanics
Full text linkWe study the maximally supersymmetric Yang-Mills theory on Sd using supersymmetric localisation and holography. We argue that the analytic continuation in dimension to d = 1 yields a Euclidean version of the BMN matrix quantum mechanics. This system can be analysed at large N using supersymmetric localisation and leads to explicit results for the free energy on Sd and the expectation value of supersymmetric Wilson loops. We show how these results can be reproduced at strong gauge coupling using holography by employing spherical D-brane solutions. We construct these solutions for any value of d using an effective supergravity description and pay particular attention to the subtleties arising in the d → 1 limit. Our results have implications for the BMN matrix quantum mechanics and the physics of circular D0-branes
Precision holography for N=2∗ on S 4 from type IIB supergravity
No full textAbstract We find a new supersymmetric solution of type IIB supergravity which is holographically dual to the planar limit of the four-dimensional N=2∗ supersymmetric Yang-Mills theory on S 4. We study a probe fundamental string in this background which is dual to a supersymmetric Wilson loop in the N=2∗ theory. Using holography we calculate the expectation value of this line operator to leading order in the ’t Hooft coupling. The result is a non-trivial function of the mass parameter of the N=2∗ theory that precisely matches the result from supersymmetric localization
The conformal manifold of S-folds in string theory
No full textWe continue the holographic exploration of the conformal manifold of 3d N = 2 S-fold SCFTs constructed by gauging the flavor symmetry of the Gaiotto-Witten T[U(N)] theory. We show how to uplift the two-parameter family of AdS4 vacua dual to this conformal manifold to 10d backgrounds of type IIB supergravity. We use these uplifted solutions to shed new light on the mysterious nature of the infinite distance limit on the conformal manifold and to study probe strings and D3-branes. This analysis uncovers an intriguing structure of the S3 partition function of the S-fold SCFTs which resembles the giant graviton expansion of the superconformal index of 4d N = 4 SYM. We also show how to each member of the family of supersymmetric AdS4 vacua one can associate a consistent truncation to 4d N = 2 gauged supergravity and use this result, in conjunction with holography, to calculate the large N partition function of the 3d S-fold SCFT on compact Euclidean manifolds. Finally, we generalize the supersymmetric AdS4 vacua to a four-parameter family of non-supersymmetric AdS4 solutions
Holographic 3d Conformal Manifolds
Full text linkWe construct and study several examples of continuous families of AdS
solutions of four-dimensional maximal gauged supergravity.
These backgrounds provide the holographic descriptions of conformal manifolds
of the dual 3d SCFTs. The solutions we study can be uplifted
to type IIB supergravity where they arise from D3-branes wrapping an with
an S-duality twist. We find the spectrum of low lying operators in the 3d
SCFTs as a function of the exactly marginal coupling and
discuss the structure of the corresponding superconformal multiplets. Using
string theory techniques we also study additional examples of continuous
families of AdS vacua in type IIB and massive type IIA
supergravity.Comment: 37 page
