Renormalized AdS gravity and holographic entanglement entropy of even-dimensional CFTs
(Springer Verlag, 2019-10)
We derive a general formula for renormalized entanglement entropy in even- dimensional CFTs holographically dual to Einstein gravity in one dimension higher. In order to renormalize, we adapt the Kounterterm method to ...
Baryon superfluids in AdS/CFT with flavor
(2017-01-01)
Baryonic matter is notoriously difficult to deal with in the large-N limit, as baryons become operators of very large dimension with N fields in the fundamental representation. This issue is also present in gauge/gravity ...
Fronsdal fields from gauge functions in Vasiliev's higher spin gravity
(2019)
In this paper, we revisit a number of issues in Vasiliev's theory related to gauge functions, ordering schemes, and the embedding of Fronsdal fields into master fields. First, we parametrize a broad equivalence class of ...
Cosmic acceleration from second order gauge gravity

CFT correlators from shape deformations in Cubic Curvature Gravity
(Springer Science and Business Media Deutschland GmbH, 2022-11)
We find a covariant expression for the universal part of the holographic entanglement entropy which is valid for CFTs dual to generic higher curvature gravities in up to five bulk dimensions. We use this functional to ...
Gravitational Energy-Momentum Density in Teleparallel Gravity
(2000-05-15)
In the context of a gauge theory for the translation group, a conserved energy-momentum gauge current for the gravitational field is obtained. It is a true spacetime and gauge tensor, and transforms covariantly under global ...
Cosmic acceleration from second order gauge gravity
(Springer, 2011-03-01)
We construct a phenomenological theory of gravitation based on a second order gauge formulation for the Lorentz group. The model presents a long-range modification for the gravitational field leading to a cosmological model ...
