Remarks on holographic models of the Kerr-AdS geometry

Julián Barragán Amado, Bruno Carneiro da Cunha, Elisabetta Pallante

We study the low-temperature limit of scalar perturbations of the Kerr-AdS black-hole for generic rotational parameters. We motivate the study by considering real-time hologr…

On the Kerr-AdS/CFT correspondence

Julián Barragán Amado, Bruno Carneiro da Cunha, Elisabetta Pallante

We review the relation between four-dimensional global conformal blocks and field propagation in . Following the standard argument that marginal perturbations should b…

Large gravitons and near-horizon diffeomorphisms

Bruno Carneiro da Cunha, Filipe Rudrigues

Usual gauge fixing procedures in classical general relativity rely on the existence of solutions of a second order wave equation. We propose to use the equation to relate asymptoti…

Kerr-de Sitter Greybody Factors via Isomonodromy

Bruno Carneiro da Cunha, Fábio Novaes

Scattering data can be generically described in terms of monodromies. Here we obtain scattering amplitudes for conformally coupled scalar fields in Kerr-de Sitter black holes using…

Kerr Scattering Coefficients via Isomonodromy

Bruno Carneiro da Cunha, Fábio Novaes

We study the scattering of a massless scalar field in a generic Kerr background. Using a particular gauge choice based on the current conservation of the radial equation, we give a…

On the Six-dimensional Kerr Theorem and Twistor Equation

Bruno Carneiro da Cunha

The Kerr theorem is revisited as part of the twistor program in six dimensions. The relationship between pure spinors and integrable 3-planes is investigated. The real condition fo…

Killing Horizons and Spinors

Bruno Carneiro da Cunha, Amilcar de Queiroz

We study the near horizon geometry of generic Killing horizons constructing suitable coordinates and taking the appropriate scaling limit. We are able to show that the geometry wil…

Holography as Cutoff: a proposal for measure of inflationary universes

Fábio Novaes, Bruno Carneiro da Cunha

We propose the holographic principle as a dynamical cutoff for any quantum theory of gravity with a geometric description at low energies, incorporating ideas of effective field th…

Kerr-CFT From Black-Hole Thermodynamics

Bruno Carneiro da Cunha, Amilcar R. de Queiroz

We analyze the near-horizon limit of a general black hole with two commuting killing vector fields in the limit of zero temperature. We use black hole thermodynamics methods to rel…

Dwelling on de Sitter

Bruno Carneiro da Cunha

A careful reduction of the three-dimensional gravity to the Liouville description is performed, where all gauge fixing and on-shell conditions come from the definition of asymptoti…

Three Dimensional de Sitter Gravity and the Correspondence

Bruno Carneiro da Cunha

Certain aspects of three dimensional asymptotically de Sitter spaces are studied, with emphasis on the mapping between gravity observables and the representation of the conformal s…

Inflation and Holography in String Theory

Bruno Carneiro da Cunha

The encoding of an inflating patch of space-time in terms of a dual theory is discussed. Following Bousso's interpretation of the holographic principle, we find that those are gene…
