Higher-dimensional BKL dynamics in AdS black holes
Elena Cáceres, Ángel J. Murcia, Ayan K. Patra +1
Chaotic BKL dynamics provides a canonical description of the approach to spacelike singularities as a sequence of Kasner epochs grouped into eras. While this paradigm is well estab…
Anisotropic critical points from holography
Dimitrios Giataganas, Umut Gürsoy, Claire Moran +2
We present a comprehensive analysis of generic 5-dimensional Einstein-Maxwell-Dilaton-Axion (EMDA) holographic theories with exponential couplings. We find and classify exact, anal…
Cosmology inside a black hole: adding matter on the brane
José L. F. Barbón, Ayan K. Patra, Juan F. Pedraza +1
Braneworlds inside an AdS black hole provide simple models where a closed cosmology can be encoded in a dual field theory. Previous studies have focused on pure-tension branes, whe…
Kasner eons with matter: holographic excursions to the black hole singularity
Elena Cáceres, Ángel J. Murcia, Ayan K. Patra +1
Recent work has shown that introducing higher-curvature terms to the Einstein-Hilbert action causes the approach to a space-like singularity to unfold as a sequence of Kasner eons.…
Diving inside holographic metals
Javier Carballo, Ayan K. Patra, Juan F. Pedraza
We investigate the gravitational dual of a fermionic field theory at finite temperature and charge density in two spatial dimensions, subject to a deformation by a relevant scalar…
