Yang-Mills instantons in Kaehler spaces with one holomorphic isometry
Samuele Chimento, Tomas Ortin, Alejandro Ruiperez
We consider self-dual Yang-Mills instantons in 4-dimensional Kaehler spaces with one holomorphic isometry and show that they satisfy a generalization of the Bogomol'nyi equation fo…
Non-perturbative decay of Non-Abelian hair
Pablo A. Cano, Tomas Ortín
We construct a solution of Heterotic supergravity which interpolates between two different AdS geometries corresponding to the near-horizon limits of…
Dyonic black holes at arbitrary locations
P. Meessen, T. Ortín, P. F. Ramírez
We construct and study stationary, asymptotically flat multicenter solutions describing regular black holes with non-Abelian hair (colored magnetic-monopole and dyon fields) in two…
Higher order gravities and the Strong Equivalence Principle
Tomas Ortin
We show that, in all metric theories of gravity with a general covariant action, gravity couples to the gravitational energy-momentum tensor in the same way it couples to the matte…
A gravitating Yang-Mills instanton
Pablo A. Cano, Tomas Ortin, Pedro F. Ramirez
We present an asymptotically flat, spherically symmetric, static, globally regular and horizonless solution of SU-gauged supergravity. The SU gauge fi…
Non-Abelian black holes in string theory
Pablo A. Cano, Patrick Meessen, Tomas Ortin +1
We study a family of 5-dimensional non-Abelian black holes that can be obtained by adding an instanton field to the well-known D1D5W Abelian black holes. Naively, the non-Abelian f…
