Gauged R-symmetry and its anomalies in 4D N=1 supergravity and phenomenological implications
I. Antoniadis, D. M. Ghilencea, R. Knoops
We consider a class of models with gauged U(1)_R symmetry in 4D N=1 supergravity that have, at the classical level, a metastable ground state, an infinitesimally small (tunable) po…
Rholography, Black Holes and Scherk-Schwarz
Nava Gaddam, Alessandra Gnecchi, Stefan Vandoren +1
We present both the macroscopic and microscopic description of a class of near-extremal asymptotically flat black hole solutions in four (or five) dimensional gauged supergravity w…
Two Wave Functions and dS/CFT on S^1 x S^2
Gabriele Conti, Thomas Hertog
We evaluate the tunneling and Hartle-Hawking wave functions on S^1 x S^2 boundaries in Einstein gravity with a positive cosmological constant. In the large overall volume limit the…
Fatal attraction: more on decaying anti-branes
Ulf H. Danielsson, Thomas Van Riet
We elaborate on the decay of branes inside throat geometries that are supported by flux carrying charges opposite to the brane. Our main point is that such backgrounds necessarily…
Non-SUSY fractional branes
Stanislav Kuperstein, Brecht Truijen, Thomas Van Riet
We consider a simplified Ansatz for supergravity solutions describing fractional p-brane solutions (throat geometries supported by fluxes) for various p. For p=3 the Ansatz capture…
On bounds and boundary conditions in the continuum Landau gauge
D. Dudal, M. S. Guimaraes, I. F. Justo +1
In this note, we consider the Landau gauge in the continuum formulation. Our purposes are twofold. Firstly, we try to work out the consequences of the recently derived Cucchieri-Me…
Holographic Entanglement Entropy from 2d CFT: Heavy States and Local Quenches
Curtis T. Asplund, Alice Bernamonti, Federico Galli +1
We consider the entanglement entropy in 2d conformal field theory in a class of excited states produced by the insertion of a heavy local operator. These include both high-energy e…
The melting of charmonium in a magnetic field from an effective AdS/QCD model
David Dudal, Thomas G. Mertens
We study the influence of a background magnetic field on the melting of the J/psi vector meson by introducing a Born-Infeld modification of the soft-wall model. Out of the three po…
Wilson lines and Chern-Simons flux in explicit heterotic Calabi-Yau compactifications
Fabio Apruzzi, Fridrik Freyr Gautason, Susha Parameswaran +1
We study to what extent Wilson lines in heterotic Calabi-Yau compactifications lead to non-trivial H-flux via Chern-Simons terms. Wilson lines are basic ingredients for Standard Mo…
On the relation between Volkov-Akulov and special conformal supersymmetry: a D3-brane perspective
Frederik Coomans, Bert Van Pol
We obtain the complete superconformal symmetry transformations on the worldvolume of a D3-brane in an background by using a coset superspace approach. We show tha…
Localised anti-branes in non-compact throats at zero and finite T
J. Blåbäck, U. H. Danielsson, D. Junghans +2
We investigate the 3-form singularities that are typical to anti-brane solutions in supergravity and check whether they can be cloaked by a finite temperature horizon. For anti-D3-…
Near Horizon Geometry of Strings Ending on Intersecting D8/D4-branes
John Estes, Darya Krym, Bert Van Pol
We consider solutions of massive IIA supergravity corresponding to the half-BPS intersection of D8/D4-branes with fundamental strings. The -dimensional intersection preserves…
Holographic Quenches and Fermionic Spectral Functions
N. Callebaut, B. Craps, F. Galli +4
Using holographic methods we investigate the behaviour of fermionic spectral functions of strongly coupled 2+1 dimensional field theories as both temperature and chemical potential…
Non-Perturbative Dynamics, Pair Condensation, Confinement and Dynamical Masses in Massless QED2+1
Michaël Fanuel, Jan Govaerts
Quantum electrodynamics in three spacetime dimensions, with one massless fermion species, is studied using a non-perturbative variational approach. Quantization of the theory follo…
The N = 1 Supersymmetric Wong Equations and the Non-Abelian Landau Problem
Michaël Fanuel, Jan Govaerts, Gabriel Y. H. Avossevou +1
A Lagrangian formulation is given extending to N = 1 supersymmetry the motion of a charged point particle with spin in a non-abelian external field. The classical formulation is co…
Spin(7)-manifolds in compactifications to four dimensions
Mariana Graña, C. S. Shahbazi, Marco Zambon
We describe off-shell M-theory compactifications down to four dimensions in terms of eight-dimensional manifolds equipped with a topological -structure. Mo…
Symplectic Deformations of Gauged Maximal Supergravity
Gianguido Dall'Agata, Gianluca Inverso, Alessio Marrani
We identify the space of symplectic deformations of maximal gauged supergravity theories. Coordinates of such space parametrize inequivalent supergravity models with the same gauge…
Holographic Signatures of Cosmological Singularities
Netta Engelhardt, Thomas Hertog, Gary T. Horowitz
To gain insight in the quantum nature of cosmological singularities, we study anisotropic Kasner solutions in gauge/gravity duality. The dual description of the bulk evolution towa…
No Fermionic Wigs for BPS Attractors in 5 Dimensions
Lorenzo G. C. Gentile, Pietro A. Grassi, Alessio Marrani +2
We analyze the fermionic wigging of 1/2-BPS (electric) extremal black hole attractors in N=2, D=5 ungauged Maxwell-Einstein supergravity theories, by exploiting anti-Killing spinor…
Gauged R-symmetry and de Sitter vacua in supergravity and string theory
Ignatios Antoniadis, Rob Knoops
A new class of metastable de Sitter vacua is presented and analyzed in N =1 supergravity and string theory with tunable (infinitesimally small) value of the cosmological constant.…
Iwasawa nilpotency degree of non compact symmetric cosets in N-extended Supergravity
Sergio Luigi Cacciatori, Bianca Letizia Cerchiai, Sergio Ferrara +1
We analyze the polynomial part of the Iwasawa realization of the coset representative of non compact symmetric Riemannian spaces. We start by studying the role of Kostant's princip…
Comments on scale and conformal invariance in four dimensions
Adam Bzowski, Kostas Skenderis
There has been recent interest in the question of whether four dimensional scale invariant unitary quantum field theories are actually conformally invariant. In this note we presen…
A note on smeared branes in flux vacua and gauged supergravity
Ulf H. Danielsson, Giuseppe Dibitetto, Marco Fazzi +1
In the known examples of flux vacua with calibrated spacetime-filling sources (branes or orientifold planes), one can smear the source in order to perform a standard KK reduction a…
