BPS domain walls from backreacted orientifolds

Johan Blåbäck, Bert Janssen, Thomas Van Riet +1

Compactifications with D-brane and orientifold sources lead to standard gauged supergravity theories if the sources are smeared over the internal directions. It is therefore of int…

Localization at Large N

J. G. Russo, K. Zarembo

We review how localization is used to probe holographic duality and, more generally, non-perturbative dynamics of four-dimensional N=2 supersymmetric gauge theories in the planar l…

An alternative to anti-branes and O-planes?

Ulf Danielsson, Giuseppe Dibitetto

In this paper we consider type IIA compactifications in the isotropic Z2 x Z2 orbifold with a flux-induced perturbative superpotential combined with non-perturbative effects. Witho…

De Sitter Vacua from Non-perturbative Flux Compactifications

Johan Blåbäck, Diederik Roest, Ivonne Zavala

We present stable de Sitter solutions of supergravity in a geometric type IIB duality frame with the addition of non-perturbative contributions. Contrary to the s…

Three-dimensional N=2 supergravity theories: From superspace to components

Sergei M. Kuzenko, Ulf Lindstrom, Martin Rocek +2

For general off-shell N=2 supergravity-matter systems in three spacetime dimensions, a formalism is developed to reduce the corresponding actions from superspace to components. The…

We compute the three-point structure constants for short primary operators of N=4 super Yang-Mills theory to leading order in the inverse coupling by mapping the problem to a flat-…

Correlation Function of Circular Wilson Loops at Strong Coupling

Amit Dekel, Thomas Klose

We study the correlation function of two circular Wilson loops at strong coupling in N=4 super Yang-Mills theory. Using the AdS/CFT correspondence, the problem maps to finding the…

A note on M2-branes in opposite charge

Johan Blåbäck

The flux singularity that arise when branes are put in an oppositely charged background is a wildly discussed issue and in this paper the problem is investigated further. New AdS w…

Massive N=2 Gauge Theories at Large N

J. G. Russo, K. Zarembo

Using exact results obtained from localization on S^4, we explore the large N limit of N=2 super-Yang-Mills theories with massive matter multiplets. We focus on three cases: N=2* t…

Yangian Symmetry of smooth Wilson Loops in N=4 super Yang-Mills Theory

Dennis Muller, Hagen Munkler, Jan Plefka +2

We show that appropriately supersymmetrized smooth Maldacena-Wilson loop operators in N=4 super Yang-Mills theory are invariant under a Yangian symmetry Y[psu(2,2|4)] built upon th…

Inhomogeneous holographic thermalization

V. Balasubramanian, A. Bernamonti, J. de Boer +6

The sudden injection of energy in a strongly coupled conformal field theory and its subsequent thermalization can be holographically modeled by a shell falling into anti-de Sitter…

Comments on World-Sheet Form Factors in AdS/CFT

Thomas Klose, Tristan McLoughlin

We study form factors in the light-cone gauge world-sheet theory for strings in AdS_5 x S^5. We perturbatively calculate the two-particle form factor in a closed su(2) sector to on…

5D Super Yang-Mills on Sasaki-Einstein manifolds

Jian Qiu, Maxim Zabzine

On any simply connected Sasaki-Einstein five dimensional manifold one can construct a super Yang-Mills theory which preserves at least two supersymmetries. We study the special cas…

Inhomogeneous Thermalization in Strongly Coupled Field Theories

V. Balasubramanian, A. Bernamonti, J. de Boer +6

To describe theoretically the creation and evolution of the quark-gluon plasma, one typically employs three ingredients: a model for the initial state, non-hydrodynamic early time…

5D super Yang-Mills theory and the correspondence to AdS/CFT

Joseph A. Minahan, Anton Nedelin, Maxim Zabzine

We study the relation between 5D super Yang-Mills theory and the holographic description of 6D (2,0) superconformal theory. We start by clarifying some issues related to the locali…
