Gravitating Non-abelian Solitons and Hairy Black Holes in Higher Dimensions
This is a short review of classical solutions with gravitating Yang-Mills fields in D > 4 spacetime dimensions. The simplest SO(4) symmetric particlelike and SO(3) symmetric vortex type solutions in the Einstein-Yang-Mills theory in D = 5 are considered, and their various generalizations with or without an event horizon, for other symmetries, in more general theories, and also in D > 5 are desc...
متن کاملHairy Black Holes, Horizon Mass and Solitons
Properties of the horizon mass of hairy black holes are discussed with emphasis on certain subtle and initially unexpected features. A key property suggests that hairy black holes may be regarded as ‘bound states’ of ordinary black holes without hair and colored solitons. This model is then used to predict the qualitative behavior of the horizon properties of hairy black holes, to provide a phy...
متن کاملGravitating Non-Abelian Solitons and Black Holes with Yang-Mills Fields
We present a review of gravitating particle-like and black hole solutions with nonAbelian gauge fields. The emphasis is given to the description of the structure of the solutions and to the connection with the results of flat space soliton physics. We describe the Bartnik-McKinnon solitons and the non-Abelian black holes arising in the Einstein-Yang-Mills theory, and consider their various gene...
متن کاملThe cosmological gravitating σ model : solitons and black holes
We derive and analyze exact static solutions to the gravitating O(3) σ model with cosmological constant in (2+1) dimensions. Both signs of the gravitational and cosmological constants are considered. Our solutions include geodesically complete spacetimes, and two classes of black holes. e-mail: [email protected] e-mail: [email protected]
متن کاملOn the linear stability of solitons and hairy black holes with a negative cosmological constant: the even-parity sector
Using a recently developed perturbation formalism based on curvature quantities, we complete our investigation of the linear stability of black holes and solitons with Yang-Mills hair and a negative cosmological constant. We show that those solutions which have no linear instabilities under oddand even-parity spherically symmetric perturbations remain stable under evenparity, linear, non-spheri...
