Holographic Wilson Loops in Symmetric Representations in N = 2* Super-Yang-Mills Theory

Xinyi Chen-Lin, Amit Dekel, Konstantin Zarembo

We construct the D3-brane solution in the holographic dual of the N = 2* theory that describes Wilson lines in symmetric representations of the gauge group. The results perfectly a…

One-point Functions in AdS/dCFT from Matrix Product States

Isak Buhl-Mortensen, Marius de Leeuw, Charlotte Kristjansen +1

One-point functions of certain non-protected scalar operators in the defect CFT dual to the D3-D5 probe brane system with k units of world volume flux can be expressed as overlaps…

Complete construction of magical, symmetric and homogeneous N=2 supergravities as double copies of gauge theories

Marco Chiodaroli, Murat Gunaydin, Henrik Johansson +1

We show that scattering amplitudes in magical, symmetric or homogeneous N=2 Maxwell-Einstein supergravities can be obtained as double copies of two gauge theories, using the framew…

Localizing gauge theories on

Joseph A. Minahan

We conjecture the form of the one-loop determinants for localized gauge theories with eight supersymmetries on -dimensional spheres. Combining this with results for the localize…

Overlaps of Partial Neel States and Bethe States

O. Foda, K. Zarembo

Partial Neel states are generalizations of the ordinary Neel (classical anti-ferromagnet) state that can have arbitrary integer spin. We study overlaps of these states with Bethe s…

Generalised Geometry and Flux Vacua

Magdalena Larfors

This note discusses the connection between generalised geometry and flux compactifications of string theory. Firstly, we explain in a pedestrian manner how the supersymmetry constr…

Hodge Numbers for CICYs with Symmetries of Order Divisible by 4

Philip Candelas, Andrei Constantin, Challenger Mishra

We compute the Hodge numbers for the quotients of complete intersection Calabi-Yau three-folds by groups of orders divisible by 4. We make use of the polynomial deformation method…

On the construction of charged operators inside an eternal black hole

Monica Guica, Daniel L. Jafferis

We revisit the holographic construction of (approximately) local bulk operators inside an eternal AdS black hole in terms of operators in the boundary CFTs. If the bulk operator ca…

Notes on Super Killing Tensors

P. S. Howe, U. Lindström

The notion of a Killing tensor is generalised to a superspace setting. Conserved quantities associated with these are defined for superparticles and Poisson brackets are used to de…

Spontaneously Broken Yang-Mills-Einstein Supergravities as Double Copies

Marco Chiodaroli, Murat Gunaydin, Henrik Johansson +1

Color/kinematics duality and the double-copy construction have proved to be systematic tools for gaining new insight into gravitational theories. Extending our earlier work, in thi…

An elliptic Virasoro symmetry in 6d

Fabrizio Nieri

We define an elliptic deformation of the Virasoro algebra. We argue that the Nekrasov partition function reproduces the chiral blocks of this alge…

The Family Problem: Hints from Heterotic Line Bundle Models

Andrei Constantin, Andre Lukas, Challenger Mishra

Within the class of heterotic line bundle models, we argue that N=1 vacua which lead to a small number of low-energy chiral families are preferred. By imposing an upper limit on th…

Chern-Simons Improved Hamiltonians for Strings in Three Space Dimensions

Ivan Gordeli, Dmitry Melnikov, Antti Niemi +1

The Frenet equation governs the extrinsic geometry of a string in three-dimensional ambient space in terms of the curvature and torsion, which are both scalar functions under strin…

Poisson Hierarchy of Discrete Strings

Theodora Ioannidou, Antti Niemi

The Poisson geometry of a discrete string in three dimensional Euclidean space is investigated. For this the Frenet frames are converted into a spinorial representation, the discre…

All gaugings and stable de Sitter in D=7 half-maximal supergravity

Giuseppe Dibitetto, Jose J. Fernández-Melgarejo, Diego Marqués

We study the general formulation of gauged supergravity in seven dimensions with sixteen supercharges keeping duality covariance by means of the embedding tensor formalism. We firs…

Universal dS vacua in STU-models

J. Blåbäck, U. H. Danielsson, G. Dibitetto +1

Stable de Sitter solutions in minimal F-term supergravity are known to lie close to Minkowski critical points. We consider a class of STU-models arising from type IIB compactificat…
