Chaos in Horndeski cosmologies
Mikhail S. Volkov
We analyze how a scalar field can affect the chaotic behaviour of homogeneous and isotropic Bianchi IX cosmologies. It is known that a massless, minimally coupled scalar field remo…
Existence of spinning solitons in field theory
Mikhail S. Volkov
The first results, both positive and negative, recently obtained in the area of constructing stationary spinning solitons in flat Minkowski space in 3+1 dimensions are discussed.
Rotating solitons and non-rotating, non-static black holes
O. Brodbeck, M. Heusler, N. Straumann +1
It is shown that the non-Abelian black hole solutions have stationary generalizations which are parameterized by their angular momentum and electric Yang-Mills charge. In particula…
Computation of the winding number diffusion rate due to the cosmological sphaleron
Mikhail S. Volkov
A detailed quantitative analysis of the transition process mediated by a sphaleron type non-Abelian gauge field configuration in a static Einstein universe is carried out. By exami…
Odd-Parity Negative Modes of Einstein-Yang-Mills Black Holes and Sphalerons
Mikhail S. Volkov, Dmitri D. Gal'tsov
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…
Einstein-Yang-Mills Sphalerons and Level Crossing
Mikhail S. Volkov
The fermion energy spectrum along paths which connect topologically distinct vacua in the Einstein-Yang-Mills theory passing through the gravitational sphaleron equilibrium solutio…
