Holographic torus entanglement and its RG flow

Pablo Bueno, William Witczak-Krempa

We study the universal contributions to the entanglement entropy (EE) of 2+1d and 3+1d holographic conformal field theories (CFTs) on topologically non-trivial manifolds, focusing…

Entanglement equilibrium for higher order gravity

Pablo Bueno, Vincent S. Min, Antony J. Speranza +1

We show that the linearized higher derivative gravitational field equations are equivalent to an equilibrium condition on the entanglement entropy of small spherical regions in vac…

Non-perturbative aspects of Euclidean Yang-Mills theories in linear covariant gauges: Nielsen identities and a BRST invariant two-point correlation function

M. A. L. Capri, D. Dudal, A. D. Pereira +5

In order to construct a gauge invariant two-point function in a Yang-Mills theory, we propose the use of the all-order gauge invariant transverse configurations A^h. Such configura…

Is inflation from unwinding fluxes IIB?

Fridrik Freyr Gautason, Marjorie Schillo, Thomas Van Riet

In this paper we argue that the mechanism of unwinding inflation is naturally present in warped compactifications of type IIB string theory with local throats. The unwinding of flu…

Holography, Brane Intersections and Six-dimensional SCFTs

Nikolay Bobev, Giuseppe Dibitetto, Fridrik Freyr Gautason +1

We study supersymmetric intersections of NS5-, D6- and D8-branes in type IIA string theory. We focus on the supergravity description of this system and identify a "near horizon" li…

Confining gauge theories and holographic entanglement entropy with a magnetic field

David Dudal, Subhash Mahapatra

We consider the soft wall model for a heuristic holographical modelling of a confining gauge theory and discuss how the introduction of a (constant) magnetic field influences the (…

Black holes with halos

Ruben Monten, Chiara Toldo

We present new AdS4 black hole solutions in N = 2 gauged supergravity coupled to vector and hypermultiplets. We focus on a particular consistent truncation of M-theory on the homog…

Deconfinement and chiral transition in AdS/QCD wall models supplemented with a magnetic field

David Dudal, Diego Rocha Granado, Thomas G. Mertens

We discuss the phenomenon of (inverse) magnetic catalysis for both the deconfinement and chiral transition. We discriminate between the hard and soft wall model, which we suitably…

Large-N correlation functions in superconformal QCD

Marco Baggio, Vasilis Niarchos, Kyriakos Papadodimas +1

We study extremal correlation functions of chiral primary operators in the large-N SU(N) superconformal QCD theory and present new results based on supersymmetric lo…

A Geometric Formulation of Supersymmetry

Daniel Z. Freedman, Diederik Roest, Antoine Van Proeyen

The scalar fields of supersymmetric models are coordinates of a geometric space. We propose a formulation of supersymmetry that is covariant with respect to reparametrizations of t…

Mass Formulae for Broken Supersymmetry in Curved Space-Time

Sergio Ferrara, Antoine Van Proeyen

We derive the mass formulae for , matter-coupled Supergravity for broken (and unbroken) Supersymmetry in curved space-time. These formulae are applicable to de Si…

The NUTs and Bolts of Squashed Holography

Nikolay Bobev, Thomas Hertog, Yannick Vreys

We evaluate the partition function of the free O(N) model on a two-parameter family of squashed three spheres. We also find new solutions of general relativity with negative cosmol…

Aspects of general higher-order gravities

Pablo Bueno, Pablo A. Cano, Vincent S. Min +1

We study several aspects of higher-order gravities constructed from general contractions of the Riemann tensor and the metric in arbitrary dimensions. First, we use the fast-linear…

Four-dimensional black holes in Einsteinian cubic gravity

Pablo Bueno, Pablo A. Cano

We construct static and spherically symmetric generalizations of the Schwarzschild- and Reissner-Nordström-(Anti-)de Sitter (RN-(A)dS) black-hole solutions in four-dimensional Eins…

Unstoppable brane-flux decay of branes

U. H. Danielsson, F. F. Gautason, T. Van Riet

We investigate branes inside a flux throat that carries D6 charges with the 3-form flux quantum and the Romans mass. We find that wi…

Entwinement in discretely gauged theories

V. Balasubramanian, A. Bernamonti, B. Craps +2

We develop the notion of entwinement to characterize the amount of quantum entanglement between internal, discretely gauged degrees of freedom in a quantum field theory. This conce…

Minkowski flux vacua of type II supergravities

David Andriot, Johan Blåbäck, Thomas Van Riet

We study flux compactifications of 10d type II supergravities to 4d Minkowski space-time, supported by parallel orientifold Op-planes with 3 p 8. With some restrictio…

Lorentzian Condition in Holographic Cosmology

Thomas Hertog, Ruben Monten, Yannick Vreys

We derive a sufficient set of conditions on the Euclidean boundary theory in dS/CFT for it to predict classical, Lorentzian bulk evolution at large spatial volumes. Our derivation…

Einsteinian cubic gravity

Pablo Bueno, Pablo A. Cano

We drastically simplify the problem of linearizing a general higher-order theory of gravity. We reduce it to the evaluation of its Lagrangian on a particular Riemann tensor dependi…

Comments on fake supersymmetry

Juan Diaz Dorronsoro, Brecht Truijen, Thomas Van Riet

Flat domain walls and spherical black holes are solutions to coupled second-order ODE's of the Hamiltonian form. Hamilton-Jacobi theory then implies that first-order flow equations…

Equivalence of Emergent de Sitter Spaces from Conformal Field Theory

Curtis T. Asplund, Nele Callebaut, Claire Zukowski

Recently, two groups have made distinct proposals for a de Sitter space that is emergent from conformal field theory (CFT). The first proposal is that, for two-dimensional holograp…
