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…
General fluctuations of the heterotic pure spinor string on curved backgrounds
Osvaldo Chandia
The general fluctuations, in the form of vertex operators, for the heterotic superstring in the pure spinor formalism are considered. The case of a flat background is reviewed and…
Three-dimensional Poincaré supergravity and -extended supersymmetric BMS algebra
Ricardo Caroca, Patrick Concha, Octavio Fierro +1
A new approach for obtaining the three-dimensional Chern-Simons supergravity for the Poincaré algebra is presented. The -extended Poincaré supergravity is obtained by…
Four-dimensional Traversable Wormholes and Bouncing Cosmologies in Vacuum
Andres Anabalon, Julio Oliva
In this letter we point out the existence of solutions to General Relativity with a negative cosmological constant in four dimensions, which contain solitons as well as traversable…
Thermodynamics of Charged, Rotating, and Accelerating Black Holes
Andres Anabalon, Finnian Gray, Ruth Gregory +2
We show how to obtain a consistent thermodynamic description of accelerating asymptotically AdS black holes, extending our previous results by including charge and rotation. We fin…
Semi-simple enlargement of the algebra from a Chern-Simons theory
Patrick Concha, Nelson Merino, Evelyn Rodríguez +2
In this work we present a BMS-like ansatz for a Chern-Simons theory based on the semi-simple enlargement of the Poincaré symmetry, also known as AdS-Lorentz algebra. We start by sh…
