New AdS Vacua in Dyonic ISO(7) Gauged Supergravity
Nikolay Bobev, Thomas Fischbacher, Fridrik Freyr Gautason +1
We identify 219 AdS solutions in four-dimensional dyonically gauged ISO(7) supergravity and present some of their properties. One of the new solutions preserves…
Kaluza-Klein Spectroscopy for the Leigh-Strassler SCFT
Nikolay Bobev, Emanuel Malek, Brandon Robinson +2
We apply recently developed tools from exceptional field theory to calculate the full Kaluza-Klein spectrum of the AdS Pilch-Warner solution of type IIB supergravity. Through t…
Novel higher-curvature variations of inflation
Pablo A. Cano, Kwinten Fransen, Thomas Hertog
We put forward novel extensions of Starobinsky inflation, involving a class of 'geometric' higher-curvature corrections that yield second-order Friedmann-Lemaître equations and sec…
Higher-Derivative Supergravity, Wrapped M5-branes, and Theories of Class
Nikolay Bobev, Anthony M. Charles, Dongmin Gang +2
We study the interplay between four-derivative 4d gauged supergravity, holography, wrapped M5-branes, and theories of class . Using results from Chern-Simons theory on…
Geometry of quantum complexity
Roberto Auzzi, Stefano Baiguera, G. Bruno De Luca +3
Computational complexity is a new quantum information concept that may play an important role in holography and in understanding the physics of the black hole interior. We consider…
A comment on no-force conditions for black holes and branes
Thomas Van Riet
In the context of the Weak Gravity Conjecture the notion of quasi-extremality for black holes and branes was recently defined as the property of having either vanishing horizon siz…
Chiral transition in the probe approximation from an Einstein-Maxwell-dilaton gravity model
Hardik Bohra, David Dudal, Ali Hajilou +1
We refine an earlier introduced 5-dimensional gravity solution capable of holographically capturing several qualitative aspects of (lattice) QCD in a strong magnetic background suc…
Comments on chiral algebras and -deformations
Nikolay Bobev, Pieter Bomans, Fridrik Freyr Gautason
Every six-dimensional SCFT on contains a set of protected operators whose correlation functions are controlled by a two-dimensional chiral algebr…
Superconformal mechanics of AdS D-brane boundstates
Delaram Mirfendereski, Joris Raeymaekers, Dieter Van den Bleeken
We explicitly construct a family of superconformal mechanics of dyonic particles, generalizing the work of Anninos et al.\,\cite{Anninos:2013nra} to an arbitrary numbe…
Spectral properties of local gauge invariant composite operators in the Yang--Mills--Higgs model
D. Dudal, D. M. van Egmond, M. S. Guimaraes +3
The spectral properties of a set of local gauge (BRST) invariant composite operators are investigated in the Yang--Mills--Higgs model with a single Higgs field in the funda…
Pure-Higgs states from the Lefschetz-Sommese theorem
I. Messamah, D. Van den Bleeken
We consider a special class of N=4 quiver quantum mechanics relevant in the description of BPS states of D4D0 branes in type II Calabi-Yau compactifications and the corresponding 4…
Conifold dynamics and axion monodromies
Marco Scalisi, Pablo Soler, Vincent Van Hemelryck +1
It has recently been appreciated that the conifold modulus plays an important role in string-phenomenological set-ups involving warped throats, both by imposing constraints on mode…
Classical de Sitter solutions in three dimensions without tachyons?
Fotis Farakos, George Tringas, Thomas Van Riet
We continue the study of compactifications of massive IIA supergravity on G2 orientifolds and demonstrate that breaking supersymmetry with anti-D2 and anti-D6 sources leads to 3d t…
Electromagnetic Quasitopological Gravities
Pablo A. Cano, Ángel Murcia
We identify a set of higher-derivative extensions of Einstein-Maxwell theory that allow for spherically symmetric charged solutions characterized by a single metric function $f(r)=…
The Unreasonable Effectiveness of Higher-Derivative Supergravity in AdS Holography
Nikolay Bobev, Anthony M. Charles, Kiril Hristov +1
We study four-derivative corrections to four-dimensional minimal gauged supergravity and show that they are controlled by two real constants. The solutions of the e…
No-scale and scale-separated flux vacua from IIA on G2 orientifolds
Fotis Farakos, George Tringas, Thomas Van Riet
We discuss flux compactifications of IIA string theory on G2 holonomy spaces with O2/O6-planes to three dimensions and find two classes of solutions: 1) No-scale Minkowski vacua fr…
Warping Wormholes with Dust: a Metric Construction of the Python's Lunch
Ning Bao, Aidan Chatwin-Davies, Grant N. Remmen
We show how wormholes in three spacetime dimensions can be customizably warped using pressureless matter. In particular, we exhibit a large new class of solutions in (2+1)-dimensio…
Euclidean Black Saddles and AdS Black Holes
Nikolay Bobev, Anthony M. Charles, Vincent S. Min
We find new asymptotically locally AdS Euclidean supersymmetric solutions of the STU model in four-dimensional gauged supergravity. These "black saddles" have an $S^1\times Σ_{…
The Casimir energy in terms of boundary quantum field theory: the QED case
David Dudal, Pablo Pais, Luigi Rosa
We revisit the path integral computation of the Casimir energy between two infinite parallel plates placed in a QED vacuum. We implement perfectly magnetic conductor boundary condi…
Supergravity in Dimensions
Edoardo Lauria, Antoine Van Proeyen
An overview of matter-coupled supergravity theories with 8 real supercharges, in 4,5 and 6 dimensions is given. The construction of the theories by superconformal meth…
Page Curve for an Evaporating Black Hole
Friðrik Freyr Gautason, Lukas Schneiderbauer, Watse Sybesma +1
A Page curve for an evaporating black hole in asymptotically flat spacetime is computed by adapting the Quantum Ryu-Takayanagi (QRT) proposal to an analytically solvable semi-class…
Holographic Uniformization and Black Hole Attractors
Nikolay Bobev, Fridrik Freyr Gautason, Klaas Parmentier
We establish an attractor mechanism for the horizon metric of asymptotically locally AdS4 supersymmetric black holes. The Kähler moduli of the metric are not fixed in the asymptoti…
Duality and Axionic Weak Gravity
Stefano Andriolo, Tzu-Chen Huang, Toshifumi Noumi +2
The axionic weak gravity conjecture predicts the existence of instantons whose actions are less than their charges in appropriate units. We show that the conjecture is satisfied fo…
