Acting with non-Abelian T-duality on the S 3 inside the AdS 5 subspace of AdS 5 × S 5 with N units of flux, we generate a new half-BPS solution with SU(2|4) symmetry that belongs to the Lin-Lunin-Maldacena class of geometries. The analysis of the asymptotics, quantised charges and probe branes in this geometry suggests an interpretation as the gravity dual to the Berenstein...

In this paper we study an AdS5 solution constructed using non-Abelian T-duality, acting on the Klebanov-Witten background. We show that this is dual to a linear quiver with two tails of gauge groups of increasing rank. The field theory dynamics arises from a D4-NS5-NS5’ brane set-up, generalizing the constructions discussed by Bah and Bobev. These realize \( \mathcal{N}=1...

In this paper we propose a linear quiver with gauge groups of increasing rank as field theory dual to the AdS 5 background constructed by Sfetsos and Thompson through non-Abelian T-duality. The formalism to study 4d \( \mathcal{N} \) = 2 SUSY CFTs developed by Gaiotto and Maldacena is essential for our proposal. We point out an interesting relation between (Hopf) Abelian and non...

In this paper we construct a new Type IIB background with an AdS 4 factor that preserves \( \mathcal{N}=4 \) Supersymmetry. This solution is obtained using a non-Abelian T-duality transformation on the Type IIA reduction of the AdS 4 × S 7 background. We interpret our configuration as a patch of a more general background with localised sources, dual to the renormalisation fixed...

We find a new \( \mathcal{N}=2 \) AdS 4 solution in M-theory supported by purely magnetic flux via a sequence of abelian and non-abelian T-dualities. This provides the second known example in this class besides the uplift of the Pernici and Sezgin solution to 7d gauged supergravity constructed in the eighties. We compute the free energy of the solution, and show that it scales as...

We construct a new AdS 4 background in Type IIB supergravity by means of a non-Abelian T-duality transformation on the Type IIA dual of ABJM. The analysis of probe and particle-like branes suggests a dual CFT in which each of the gauge groups is doubled. A common feature of non-Abelian T-duality is that in the absence of any global information coming from String Theory it gives...

We construct a supersymmetric NS5-brane wrapped on a twisted 5-sphere expanding in the CP 3 in AdS 4 × CP 3, with D0-brane charge. This configuration provides a realization of the stringy exclusion principle in terms of giant D0-branes. In the maximal case the twisted 5-sphere reduces to a CP 2 and its energy can be accounted for both by a bound state of k D4-branes wrapping the...

We analyze the holographic description of non-singlet baryons in various backgrounds with reduced supersymmetries and/or confinement. We show that they exist in all AdS5 × Y 5 backgrounds with Y5 an Einstein manifold bearing five form flux, for a number of quarks 5N/8 < k ≤ N , independently on the supersymmetries preserved. This result still holds for γi deformations. In the...

We study the effect of adding lower dimensional brane charges to the ’t Hooft monopole, di-baryon and baryon vertex configurations in \( Ad{S_4} \times {\mathbb{P}^3} \). We show that these configurations capture the background fluxes in a way that depends on the induced charges, and therefore, require additional fundamental strings in order to cancel the worldvolume tadpoles...

We consider magnetically charged baryon vertex like configurations in AdS 4 × CP 3 with a reduced number of quarks l. We show that these configurations are solutions to the classical equations of motion and are stable beyond a critical value of l. Given that the magnetic flux dissolves D0-brane charge it is possible to give a microscopical description in terms of D0-branes...
