چکیده

It is proven that there are precisely n odd-parity sphaleron-like unstable modes of the n-th Bartnik-McKinnon soliton and the n-th non-abelian black hole solution of the Einstein-Yang-Mills theory for the gauge group SU(2).

Gravitating 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...

Odd–parity negative modes of Einstein–Yang–Mills black holes and sphalerons

An analytical proof of the existence of negative modes in the odd–parity perturbation sector is given for all known non-Abelian Einstein–Yang–Mills black holes. The significance of the normalizability condition in the functional stability analysis is emphasized. The role of the odd–parity negative modes in the sphaleron interpretation of the Bartnik–McKinnon solutions is discussed. On leave fro...

The Interaction of Dirac Particles with Non-Abelian Gauge Fields and Gravity – Black Holes

We consider a static, spherically symmetric system of a Dirac particle in a classical gravitational and SU(2) Yang-Mills field. We prove that the only black-hole solutions of the corresponding Einstein-Dirac-Yang/Mills equations are the Bartnik-McKinnon black-hole solutions of the SU(2) Einstein-Yang/Mills equations; thus the spinors must vanish identically. This indicates that the Dirac partic...

Slowly Rotating Non-Abelian Black Holes

It is shown that the well-known non-Abelian static SU(2) black hole solutions have rotating generalizations, provided that the hypothesis of linearization stability is accepted. Surprisingly, this rotating branch has an asymptotically Abelian gauge field with an electric charge that cannot vanish, although the non-rotating limit is uncharged. We argue that this may be related to our second find...

Aspects of hairy black holes in spontaneously broken Einstein-Yang-Mills systems: Stability analysis and entropy considerations.

We analyze (3+1)-dimensional black-hole space-times in spontaneously broken Yang-Mills gauge theories that have been recently presented as candidates for an evasion of the scalar-no-hair theorem. Although we show that in principle the conditions for the no-hair theorem do not apply to this case, however we prove that the ‘spirit’ of the theorem is not violated, in the sense that there exist ins...
