On rotational excitations and axial deformations of BPS monopoles and Julia-Zee dyons
M. Heusler, N. Straumann, M. Volkov
It is shown that Julia-Zee dyons do not admit slowly rotating excitations. This is achieved by investigating the complete set of stationary excitations which can give rise to non-v…
Stability Analysis of New Solutions of the EYM system with Cosmological Constant
O. Brodbeck, M. Heusler, G. Lavrelashvili N. Straumann +1
We analyze the stability properties of the purely magnetic, static solutions to the Einstein--Yang--Mills equations with cosmological constant. It is shown that all three classes o…
Instability of Gravitating Sphalerons
P. Boschung, O. Brodbeck, F. Moser +2
We prove the instability of the gravitating regular sphaleron solutions of the Einstein-Yang-Mills-Higgs system with a Higgs doublet, by studying the frequency spectrum of…
Einstein-Yang-Mills sphalerons and fermion number non-conservation
Mikhail S. Volkov
It is argued that the sphaleron solutions appearing in the Einstein-Yang-Mills theory are important in the transition processes at extremely high energies. Namely, when the energy…
