On the absence of supergravity solutions for localized, intersecting sources
For decades intersecting D-branes and O-planes have been playing a very important role in string phenomenology in the context of particle physics...

S-folds and AdS3 flows from the D3-brane
We investigate supersymmetric flows in type IIB supergravity that preserve an SO(2 , 2) space-time symmetry and asymptote to AdS 5 × S 5 at both...

Twisted D3-brane and M5-brane compactifications from multi-charge spindles
We construct families of supersymmetric AdS 3 × Y 7 and AdS 3 × Y 8 solutions to type IIB string theory and M-theory, respectively. Here Y 7 is an S 5 ...

S-folds and holographic RG flows on the D3-brane
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...

Electromagnetic duality and D3-brane scattering amplitudes beyond leading order
We use on-shell methods to study the non-supersymmetric and supersymmetric low-energy S-matrix on a probe D3-brane, including both the 1-loop...

Corrections to the Supergravity Action in Type IIB
In this chapter we describe the most common and best understood ways to break the no-scale structure for the tree-level scalar potential described in...

Supergravities on branes
Supergravity brane solutions allow for a generalised type of Kaluza-Klein reduction onto brane worldvolumes. The known replacement of a flat...

Comments on D3-brane holography
We revisit the idea that the quantum dynamics of open strings ending on N D3-branes in the large N limit can be described at large ‘t Hooft coupling...

Non-Lorentzian IIB supergravity from a polynomial realization of SL(2, ℝ)
We derive the action and symmetries of the bosonic sector of non-Lorentzian IIB supergravity by taking the non-relativistic string limit. We find...

A plethora of Type IIA embeddings for d = 5 minimal supergravity
We construct multiple embeddings of all solutions of d = 5 minimal (un)gauged supergravity into massive Type IIA supergravity. The internal spaces...

New superstrata from three-dimensional supergravity
We find a two-parameter family of generalized superstrata that emerge as smooth, supersymmetric solutions in three-dimensional gauged supergravity...

Holographic duals of the \( \mathcal{N} \) = 1* gauge theory
We use the long-wavelength effective theory of black branes (blackfold approach) to perturbatively construct holographic duals of the vacua of the

Small kinetic mixing in string theory
Kinetic mixing between gauge fields of different U(1) factors is a well-studied phenomenon in 4d EFT. In string compactifications with U(1)s from...

Holographic 6d co-dimension 2 defect solutions in M-theory
We consider the uplift of co-dimension two defect solutions of seven dimensional gauged supergravity to eleven dimensions, previously found by two of...

Supersymmetric AdS solitons and the interconnection of different vacua of \( \mathcal{N} \) = 4 Super Yang-Mills
We find AdS soliton solutions in 5-dimensional gauged supergravity, obtained from the S 5 compactification of type IIB, with a dilaton saturating the...

Localization on AdS3 × S2. Part I. The 4d/5d connection in off-shell Euclidean supergravity
We begin to develop the formalism of localization for the functional integral of supergravity on AdS 3 × S 2 . We show how the condition of...

Type IIA embeddings of D = 5 minimal gauged supergravity via non-Abelian T-duality
In this paper, we construct explicit Type IIA uplifts of D = 5 minimal gauged supergravity by T-dualising known Type IIB uplifts on N 5 = S 5 , T 1 , 1 and Y

Resolution à la Kronheimer of \(\mathbb {C}^3/\Gamma \) singularities and the Monge–Ampère equation for Ricci-flat Kähler metrics in view of D3-brane solutions of supergravity
In this paper, we analyze the relevance of the generalized Kronheimer construction for the gauge/gravity correspondence. We begin with the general...
