New Charged Black Holes with Conformal Scalar Hair (2009)
Anabalon, Andres, Maeda, Hideki
A new class of four-dimensional, hairy, stationary solutions of the Einstein-Maxwell-$\Lambda$ system with a conformally coupled scalar field is constructed in this paper. The metric belongs to the...
The gauge structure of Liouville theory (2009)
It is proved that Liouville theory and the two dimensional SO(2,1) gauged Wess-Zumino-Witten term are on-shell equivalent. This shed light on a possible higher dimensional generalization of the...
Anabalon, Andres, Deruelle, Nathalie, Morisawa, Yoshiyuki, Oliva, Julio, Sasaki, Misao, Tempo, David, ...
As is well-known, Kerr-Schild metrics linearize the Einstein tensor. We shall see here that they also simplify the Gauss-Bonnet tensor, which turns out to be only quadratic in the arbitrary...
Some considerations on the Mac Dowell-Mansouri action (2008)
A precise relation is established between the Stelle-West formulation of the Mac Dowell-Mansouri approach to a gauge theory of gravity and the approach based on a gauged Wess-Zumino-Witten term. In...
The Universe as a topological defect (2007)
Anabalon, Andres, Willison, Steven, Zanelli, Jorge
Four-dimensional Einstein's General Relativity is shown to arise from a gauge theory for the conformal group, SO(4,2). The theory is constructed from a topological dimensional reduction of the...
General Relativity from a gauged WZW term (2006)
Anabalon, Andres, Willison, Steven, Zanelli, Jorge
In this paper two things are done. First it is shown how a four dimensional gauged Wess-Zumino-Witten term arises from the five dimensional Einstein-Hilbert plus Gauss-Bonnet lagrangian with a...
N=4 superconformal mechanics as a Non linear Realization (2006)
Anabalon, Andres, Gomis, Joaquim, Kamimura, Kiyoshi, Zanelli, Jorge
An action for a superconformal particle is constructed using the non linear realization method for the group PSU(1,1|2), without introducing superfields. The connection between PSU(1,1|2) and black...
Interaction via reduction and nonlinear superconformal symmetry (2003)
Anabalon, Andres, Plyushchay, Mikhail S.
We show that the reduction of a planar free spin-1/2 particle system by the constraint fixing its total angular momentum produces the one-dimensional Akulov-Pashnev-Fubini-Rabinovici superconformal...
New Charged Black Holes with Conformal Scalar Hair
Anabalon, Andres, Maeda, Hideki
A general class of four dimensional, stationary solutions of the Einstein-Maxwell system with a conformally coupled scalar field is constructed in this paper. The stationary case is presented and...
