Understand

We consider homogeneous non-abelian vector fields with general potential terms in an expanding universe.

We find a mechanical analogy with a system of N interacting particles (with N the dimension of the gauge group) moving in three dimensions under the action of a central potential.
In the case of bounded and rapid evolution compared to the rate of expansion, we show by making use of a generalization of the virial theorem that for arbitrary potential and polarization pattern, the average energy-momentum tensor is always diagonal and isotropic despite the intrinsic anisotropic evolution of the vector field.
We consider also the case in which a gauge-fixing term is introduced in the action and show that the average equation of state does not depend on such a term.
