A note on the super- holographic dictionary
Alejandra Castro, Alberto Faraggi, Israel Osorio
This is a long-overdue companion paper to arXiv:1512.00073. We study the relation between Chern-Simons supergravity on AdS and two-dimensional CFT's with $\mathcal{N}…
Keeping matter in the loop in dS quantum gravity
Alejandra Castro, Ioana Coman, Jackson R. Fliss +1
We propose a mechanism that couples matter fields to three-dimensional de Sitter quantum gravity. Our construction is based on the Chern-Simons formulation of three-dimensional Euc…
Conformal field theories dual to quantum gravity with strongly coupled matter
Luis Apolo, Alexandre Belin, Suzanne Bintanja +2
A holographic conformal field theory is dual to semi-classical general relativity in Anti-de Sitter space coupled to matter fields. If the CFT factorizes in the large- limit, th…
Gravitational Anomalies in nAdS/nCFT
Alejandra Castro, Beatrix Mühlmann
We revisit the holographic description of the near horizon geometry of the BTZ black hole in AdS gravity, with a gravitational Chern-Simons term included. After a dimensional r…
Comments on AdS_2 Gravity
Alejandra Castro, Wei Song
We revisit some properties of AdS Einstein-Maxwell gravity with the aim of reconciling apparently conflicting results in prior literature. We show that the two dimensional theo…
Coupling Fields to 3D Quantum Gravity via Chern-Simons Theory
Alejandra Castro, Ioana Coman, Jackson R. Fliss +1
We propose a mechanism that couples matter fields to three-dimensional quantum gravity, which can be used for theories with a positive or negative cosmological constant. Our propos…
