The quasi-topological space of quasi-topological gravities
Pablo Bueno, Robie A. Hennigar, Matteo G. Marrone +1
We investigate general properties of quasi-topological theories of gravity involving infinite towers of polynomial densities and of their regular vacuum black hole solutions. We sh…
Thin shells in Lovelock and Quasi-topological gravities
Pablo Bueno, Pablo A. Cano, Robie A. Hennigar +2
We derive the junction conditions for spherically symmetric thin shells in Lovelock and Quasi-topological gravities along two independent routes: from the distributional form of th…
Logarithmic correction to the entropy of near-extremal higher-curvature black holes
Pablo Bueno, Pablo A. Cano, Robie A. Hennigar +3
The spherically symmetric sector of broad classes of -dimensional gravitational theories can be effectively described by general two-dimensional Horndeski theories. Exploiting t…
Higher-dimensional BKL dynamics in AdS black holes
Elena Cáceres, Ángel J. Murcia, Ayan K. Patra +1
Chaotic BKL dynamics provides a canonical description of the approach to spacelike singularities as a sequence of Kasner epochs grouped into eras. While this paradigm is well estab…
Birkhoff implies Quasi-topological
Pablo Bueno, Robie A. Hennigar, Ángel J. Murcia
Quasi-topological gravities (QTGs) are higher-curvature extensions of Einstein gravity in spacetime dimensions. Throughout the years, different notions of QTGs constructe…
Novel duality-invariant theories of electrodynamics
Ángel J. Murcia
We identify new families of duality-invariant theories of electrodynamics. We achieve this in two different ways. On the one hand, we present an algorithm to construct a one-parame…
Dynamical Formation of Regular Black Holes
Pablo Bueno, Pablo A. Cano, Robie A. Hennigar +1
We study dynamical gravitational collapse in a theory with an infinite tower of higher-derivative corrections to the Einstein-Hilbert action and we show that, under very general co…
Kasner eons with matter: holographic excursions to the black hole singularity
Elena Cáceres, Ángel J. Murcia, Ayan K. Patra +1
Recent work has shown that introducing higher-curvature terms to the Einstein-Hilbert action causes the approach to a space-like singularity to unfold as a sequence of Kasner eons.…
Generalized Siklos space-times
Bernardo Araneda, Ángel J. Murcia
Motivated by supersymmetry methods in general relativity, we study four-dimensional Lorentzian space-times with a complex Dirac spinor field satisfying a Killing-spinor-like equati…
Waves and strings in an interacting conformal chiral 2-form theory in six dimensions
Nihat Sadik Deger, Ángel J. Murcia, Dmitri P. Sorokin
In six dimensions there exists a unique one-parameter family of non-linear conformal electrodynamics for a chiral 2-form gauge field which includes (in a free-field limit) the line…
Cosmological higher-curvature gravities
Javier Moreno, Ángel J. Murcia
We examine higher-curvature gravities whose FLRW configurations are specified by equations of motion which are of second order in derivatives, just like in Einstein gravity. We nam…

Andrei Moroianu, Ángel J. Murcia, C. S. Shahbazi
We introduce a novel curvature flow, the Heterotic-Ricci flow, as the two-loop renormalization group flow of the Heterotic string common sector and study its three-dimensional comp…

Javier Moreno, Ángel J. Murcia
Generalized Quasitopological Gravities (GQTGs) are higher-order extensions of Einstein gravity in dimensions satisfying a number of interesting properties, such as possessing s…

We carry out an extensive study of the holographic aspects of any-dimensional higher-derivative Einstein-Maxwell theories in a fully analytic and non-perturbative fashion. We achie…

The three-dimensional parallel spinor flow is the evolution flow defined by a parallel spinor on a globally hyperbolic Lorentzian four-manifold. We prove that, despite the fact tha…

Pablo A. Cano, Ángel Murcia
We study nonminimal extensions of Einstein-Maxwell theory with exact electromagnetic duality invariance. Any such theory involves an infinite tower of higher-derivative terms whose…
