Ferromagnetic properties of charged vector boson condensate

Understand

Bose-Einstein condensation of W bosons in the early universe is studied.

• It is shown that, in the broken phase of the standard electroweak theory, condensed W bosons form a ferromagnetic state with aligned spins.
• In this case the primeval plasma may be spontaneously magnetized inside macroscopically large domains and form magnetic fields which may be seeds for the observed today galactic and intergalactic fields.
• However, in a modified theory, e.g.
