Semiclassical decay of de Sitter space into black holes with vortex-deformed horizons
Andrés Gomberoff, Carla Henríquez-Baez, Aldo Vera
We study the decay of de Sitter space into black holes whose horizons are dressed by BPS vortices of a action. The process is mediated by a regular Euclidean instan…
Exact black holes and black branes with bumpy horizons supported by superfluid pions
Fabrizio Canfora, Andrés Gomberoff, Carla Henríquez-Baez +1
We present exact solutions of the Einstein non-linear sigma model in spacetime dimensions, describing bumpy black holes and black branes. Using an Ansatz for superflu…
Analytic meronic black holes, gravitating solitons and higher spins in the Einstein -Yang-Mills theory
Fabrizio Canfora, Andrés Gomberoff, Marcela Lagos +1
We construct meronic black holes and solitons in the Einstein -Yang-Mills theory in and dimensions. These analytical solutions are found by combining the general…
Bondi-Metzner-Sachs invariance and electric-magnetic duality
Claudio Bunster, Andrés Gomberoff, Alfredo Pérez
We exhibit a Hamiltonian formulation, both for electromagnetism and gravitation, in which it is not required that the Bondi "news" vanish, but only that the incoming news be equal…
Meronic Einstein-Yang-Mills black hole in 5D and gravitational spin from isospin effect
Fabrizio Canfora, Andrés Gomberoff, Seung Hun Oh +2
We construct an analytic black hole solution in Einstein-Yang-Mills theory in five dimensions supporting a Meron field. The gauge field is proportional to a pure gauge and…
Regge-Teitelboim analysis of the symmetries of electromagnetic and gravitational fields on asymptotically null spacelike surfaces
Claudio Bunster, Andrés Gomberoff, Alfredo Pérez
We present a new application of the Regge-Teitelboim method for treating symmetries which are defined asymptotically. It may be regarded as complementary to the one in their origin…
