Conformal couplings of a scalar field to higher curvature terms
Julio Oliva, Sourya Ray
We present a simple way of constructing conformal couplings of a scalar field to higher order Euler densities. This is done by constructing a four-rank tensor involving the curvatu…
Gribov pendulum in the Coulomb gauge on curved spaces
Fabrizio Canfora, Alex Giacomini, Julio Oliva
In this paper the generalization of the Gribov pendulum equation in the Coulomb gauge for curved spacetimes is analyzed on static spherically symmetric backgrounds. A rigorous argu…
Black holes with gravitational hair in higher dimensions
Andres Anabalon, Fabrizio Canfora, Alex Giacomini +1
A new class of vacuum black holes for the most general gravity theory leading to second order field equations in the metric in even dimensions is presented. These space-times are l…
Birkhoff's Theorem in Higher Derivative Theories of Gravity
Julio Oliva, Sourya Ray
In this paper we present a class of higher derivative theories of gravity which admit Birkhoff's theorem. In particular, we explicitly show that in this class of theories, although…
