QNMs of scalar fields on small Reissner-Nordström-AdS black holes
Julián Barragán Amado, Bruno Carneiro da Cunha, Elisabetta Pallante
We study the quasinormal modes (QNMs) of a charged scalar field on a Reissner-Nordström-anti-de Sitter (RN-AdS) black hole in the small radius limit by using the isomonodromi…
Scalar quasinormal modes of Kerr-AdS
Julián Barragán-Amado, Bruno Carneiro da Cunha, Elisabetta Pallante
An analytic expression for the scalar quasinormal modes of the generic, spinning Kerr- black holes was previously proposed by the authors in ref. 1, in terms of tra…
Exploring the BTZ bulk with boundary conformal blocks
Bruno Carneiro da Cunha, Monica Guica
We point out a simple relation between the bulk field at an arbitrary radial position and the boundary OPE, by placing some old work by Ferrara, Gatto, Grillo and Parisi in the AdS…
Isomonodromy, Painlevé Transcendents and Scattering off of Black Holes
Fábio Novaes, Bruno Carneiro da Cunha
We apply the method of isomonodromy to study the scattering of a generic Kerr-NUT-(A)dS black hole. For generic values of the charges, the problem is related to the connection prob…
A Note on Tachyon Moduli and Closed Strings
Bruno Carneiro da Cunha
The collective behavior of the SL(2,R) covariant brane states of non-critical c=1 string theory found in a previous work, is studied in the Fermi liquid approximation. It is found…
Perturbative aspects and conformal solutions of F(R) gravity
D. Bazeia, B. Carneiro da Cunha, R. Menezes +1
We investigate perturbative aspects of gravity with a general F(R) Lagrangian, as well as nonperturbative dilatonic solutions. For the first part, we are interested in stability an…
