Regular Black Holes in Nonlocal Quasitopological Gravity
Pablo Bueno, Pablo A. Cano, Robie A. Hennigar +1
We present infinite-derivative completions of Quasitopological gravities that are ghost-free, avoid strong coupling instabilities and admit exact, spherically symmetric vacuum regu…
Quantum Solitons
Robie A. Hennigar, Ayan K. Patra, Simon F. Ross
We construct geometries describing the quantum backreaction of thermal fields in AdS. The solutions are obtained from branes in a four-dimensional AdS C-metric. They can be vie…
Buchdahl limits in theories with regular black holes
Pablo Bueno, Robie A. Hennigar, Ãngel J. Murcia +1
We study generalizations of Buchdahl's compactness limits for perfect-fluid star solutions of -dimensional Einstein gravity coupled to higher-curvature corrections. We focus on…
Regular Geometries from Singular Matter in Quasi-Topological Gravity
Pablo Bueno, Robie A. Hennigar, Ãngel J. Murcia +1
Vacuum quasi-topological gravity with infinitely many terms in the action satisfies Markov's limiting curvature hypothesis: the spherically symmetric solutions are regular and all…
Birkhoff implies Quasi-topological
Pablo Bueno, Robie A. Hennigar, Ãngel J. Murcia
Quasi-topological gravities (QTGs) are higher-curvature extensions of Einstein gravity in spacetime dimensions. Throughout the years, different notions of QTGs constructe…
Regular black hole formation in four-dimensional non-polynomial gravities
Pablo Bueno, Pablo A. Cano, Robie A. Hennigar +1
We construct four-dimensional gravity theories that resolve the Schwarzschild singularity and enable dynamical studies of nonsingular gravitational collapse. The construction emplo…
