Large spin expansion of semiclassical 3-point correlators in AdS_5 x S^5
J. G. Russo, A. A. Tseytlin
3-point correlators in AdS_5xS^5 string theory in which two states are "heavy" (have large quantum numbers) and the third is "light" (here chosen as chiral primary scalar) can be c…
Towards holographic walking from N=4 super Yang-Mills
S. Prem Kumar, David Mateos, Angel Paredes +1
We propose that a holographic description of `walking' behaviour, namely quasi-conformal dynamics relevant for technicolor models, can be obtained from relevant deformations of N=4…
p-wave Holographic Superconductors and five-dimensional gauged Supergravity
Francesco Aprile, Diego Rodriguez-Gomez, Jorge G. Russo
We explore five-dimensional and SO(6) gauged supergravities as frameworks for condensed matter applications. These theories contain cha…
SuperParticle realization of twisted N=2 SUSY algebra
Roberto Casalbuoni, Joaquim Gomis, Kiyoshi Kamimura
We construct a pseudoclassical particle model associated to the twisted N=2 SUSY algebra in four dimensions. The particle model has four kappa symmetries. Three of them can be used…
Holographic description of vacuum bubbles
Jaume Garriga
We discuss a holographic description of vacuum bubbles, with possible implications for a consistent description of the multiverse. In particular, we elaborate on the recent observa…
Higher-dimensional Rotating Charged Black Holes
Marco M. Caldarelli, Roberto Emparan, Bert Van Pol
Using the blackfold approach, we study new classes of higher-dimensional rotating black holes with electric charges and string dipoles, in theories of gravity coupled to a 2-form o…
Accelerated detectors and worldsheet horizons in AdS/CFT
Mariano Chernicoff, Angel Paredes
We use the AdS/CFT correspondence to discuss the response of an accelerated observer to the quantum vacuum fluctuations. In particular, we study heavy quarks probing a strongly cou…
Galilean symmetry in the effective theory of inflation: new shapes of non-Gaussianity
Paolo Creminelli, Guido D'Amico, Marcello Musso +2
We study the consequences of imposing an approximate Galilean symmetry on the Effective Theory of Inflation, the theory of small perturbations around the inflationary background. T…
The cosmological constant and the relaxed universe
Florian Bauer
We study the role of the cosmological constant (CC) as a component of dark energy (DE). It is argued that the cosmological term is in general unavoidable and it should not be ignor…
Cherenkov mesons as in-medium quark energy loss
Jorge Casalderrey-Solana, Daniel Fernandez, David Mateos
We recently showed that a heavy quark moving sufficiently fast through a quark-gluon plasma may lose energy by Cherenkov-radiating mesons [1]. Here we review our previous holograph…
Multi-black rings and the phase diagram of higher-dimensional black holes
Roberto Emparan, Pau Figueras
Configurations of multiple concentric black rings play an important role in determining the pattern of branchings, connections and mergers between different phases of higher-dimens…
Black stars induced by matter on a brane: exact solutions
A. A. Andrianov, M. A. Kurkov
New exact asymptotically flat solutions of five-dimensional Einstein equations with horizon are found to describe multidimensional black stars generated by matter on the brane, con…
No-dipole-hair theorem for higher-dimensional static black holes
Roberto Emparan, Seiju Ohashi, Tetsuya Shiromizu
We prove that static black holes in n-dimensional asymptotically flat spacetime cannot support non-trivial electric p-form field strengths when (n+1)/2<= p <= n-1. This implies in…
Deformations of Maxwell Superalgebras and Their Applications
Sotirios Bonanos, Joaquim Gomis, Kiyoshi Kamimura +1
We describe the Lie algebra deformations of D=4 Maxwell superalgebra that was recently introduced as the symmetry algebra of a kappa-symmetric massless superparticle in a supersymm…
Flavor from M5-branes
Bartomeu Fiol
We study various aspects of the defect conformal field theory that arises when placing a single M5-brane probe in AdS_4 x S^7. We derive the full set of fluctuation modes and dimen…
The emergence of geometry: a two-dimensional toy model
Jorge Alfaro, Domènec Espriu, Daniel Puigdomènech
We review the similarities between the effective chiral lagrangrian, relevant for low-energy strong interactions, and the Einstein-Hilbert action. We use these analogies to suggest…
Defect CFTs and holographic multiverse
Bartomeu Fiol
We investigate some aspects of a recent proposal for a holographic description of the multiverse. Specifically, we focus on the implications on the suggested duality of the fluctua…
Black Brane Viscosity and the Gregory-Laflamme Instability
Joan Camps, Roberto Emparan, Nidal Haddad
We study long wavelength perturbations of neutral black p-branes in asymptotically flat space and show that, as anticipated in the blackfold approach, solutions of the relativistic…
Quantum Fluctuations and the Unruh Effect in Strongly-Coupled Conformal Field Theories
Elena Caceres, Mariano Chernicoff, Alberto Guijosa +1
Through the AdS/CFT correspondence, we study a uniformly accelerated quark in the vacuum of strongly-coupled conformal field theories in various dimensions, and determine the resul…
Phenomenological Models of Holographic Superconductors and Hall currents
Francesco Aprile, Sebastian Franco, Diego Rodriguez-Gomez +1
We study general models of holographic superconductivity parametrized by four arbitrary functions of a neutral scalar field of the bulk theory. The models can accommodate several f…
Gauge Symmetry Breaking in Matrix Models
Harald Grosse, Fedele Lizzi, Harold Steinacker
We argue that some features of the standard model, in particular the fermion assignment and symmetry breaking, can be obtained in matrix model which describes noncommutative gauge…
Unquenched flavor in the gauge/gravity correspondence
Carlos Nunez, Angel Paredes, Alfonso V. Ramallo
Within the AdS/CFT correspondence, we review the studies of field theories with a large number of adjoint and fundamental fields, in the Veneziano limit. We concentrate in set-ups…
String theory dualities and supergravity divergences
Michael B. Green, Jorge G. Russo, Pierre Vanhove
We demonstrate how duality invariance of the low energy expansion of the four-graviton amplitude in type II string theory determines the precise coefficients of multiloop logarithm…
Models of Holographic superconductivity
Francesco Aprile, Jorge G. Russo
We construct general models for holographic superconductivity parametrized by three couplings which are functions of a real scalar field and show that under general assumptions the…
