Noncommutative Black Holes and the Singularity Problem
C. Bastos, O. Bertolami, N. C. Dias +1
A phase-space noncommutativity in the context of a Kantowski-Sachs cosmological model is considered to study the interior of a Schwarzschild black hole. Due to the divergence of th…
Non-Canonical Phase-Space Noncommutativity and the Kantowski-Sachs singularity for Black Holes
Catarina Bastos, Orfeu Bertolami, Nuno Costa Dias +1
We consider a cosmological model based upon a non-canonical noncommutative extension of the Heisenberg-Weyl algebra to address the thermodynamical stability and the singularity pro…
Writing CFT correlation functions as AdS scattering amplitudes
Joao Penedones
We explore the Mellin representation of conformal correlation functions recently proposed by Mack. Examples in the AdS/CFT context reinforce the analogy between Mellin amplitudes a…
Twisted Bethe equations from a twisted S-matrix
Changrim Ahn, Zoltan Bajnok, Diego Bombardelli +1
All-loop asymptotic Bethe equations for a 3-parameter deformation of AdS5/CFT4 have been proposed by Beisert and Roiban. We propose a Drinfeld twist of the AdS5/CFT4 S-matrix, toge…
Hermitian Yang-Mills instantons on resolutions of Calabi-Yau cones
Filipe Paccetti Correia
We study the construction of Hermitian Yang-Mills instantons over resolutions of Calabi-Yau cones of arbitrary dimension. In particular, in d complex dimensions, we present an infi…
On three-point correlation functions in the gauge/gravity duality
Miguel S. Costa, Ricardo Monteiro, Jorge E. Santos +1
We study the effect of marginal and irrelevant deformations on the renormalization of operators near a CFT fixed point. New divergences in a given operator are determined by its OP…
A scalar field condensation instability of rotating anti-de Sitter black holes
Oscar J. C. Dias, Ricardo Monteiro, Harvey S. Reall +1
Near-extreme Reissner-Nordstrom-anti-de Sitter black holes are unstable against the condensation of an uncharged scalar field with mass close to the Breitenlohner-Freedman bound. I…
Localized D-dimensional global k-defects
P. P. Avelino, D. Bazeia, R. Menezes +1
We explicitly demonstrate the existence of static global defect solutions of arbitrary dimensionality whose energy does not diverge at spatial infinity, by considering maximally sy…
Generalized self-dual Chern-Simons vortices
D. Bazeia, E. da Hora, C. dos Santos +1
We search for vortices in a generalized Abelian Chern-Simons model with a nonstandard kinetic term. We illustrate our results, plotting and comparing several features of the vortex…
Ultraspinning instability of rotating black holes
Oscar J. C. Dias, Pau Figueras, Ricardo Monteiro +1
Rapidly rotating Myers-Perry black holes in d>5 dimensions were conjectured to be unstable by Emparan and Myers. In a previous publication, we found numerically the onset of the ax…
Holographic duals of SQCD models in low dimensions
Daniel Arean, Eduardo Conde, Alfonso V. Ramallo +1
We obtain gravity duals to supersymmetric gauge theories in two and three spacetime dimensions with unquenched flavor. The supergravity solutions are generated by a set of color br…
Black holes in a box: towards the numerical evolution of black holes in AdS
Helvi Witek, Vitor Cardoso, Carlos Herdeiro +3
The evolution of black holes in "confining boxes" is interesting for a number of reasons, particularly because it mimics the global structure of Anti-de Sitter geometries. These ar…
Compactlike kinks and vortices in generalized models
D. Bazeia, E. da Hora, R. Menezes +2
This work deals with the presence of topological defects in k-field models, where the dynamics is generalized to include higher order power in the kinetic term. We investigate kink…
