A center vortex representaton of the classical SU(2) vacuum
P. Olesen
The classical massless SU(2) field theory has an infinite number of gauge equivalent representations of the vacuum. We show that among these there exists a non-perturbative center…
Some remarks on the "classical" large N limit
Poul Olesen
It has been proposed some time ago that the large limit can be understood as a ``classical limit'', where commutators in some sense approach the corresponding Poisson brackets.…
On inverse Cascades and Primordial Magnetic Fields
P. Olesen
We consider primordial spectra with simple power behaviours and show that in the Navier-Stokes and magnetohydrodynamics equations without forcing, there exists systems in three dim…
A New Perspective on Electroweak Strings
F. R. Klinkhamer, P. Olesen
The vortex solution (Z-string) of the electroweak interactions can be interpreted as the 2-dimensional sphaleron at the top of a non-contractible sphere. The same holds for another…
On Primordial Magnetic Fields of Electroweak Origin
K. Enqvist, P. Olesen
We consider Vachaspati's primordial magnetic field which is generated at the electroweak phase transition. Assuming that either the gradients of the Higgs field or, alternatively,…
