Magnetic Fields Produced by Phase Transition Bubbles in the Electroweak Phase Transition

Abstract

The electroweak phase transition, if proceeding through nucleation and growth of bubbles, should generate large scale turbulent flow, which in turn generates magnetic turbulence and hence magnetic fields on the scale of turbulent flow. We discuss the seeding of this turbulent field by the motion of the dipole charge layers in the phase transition bubble walls, and estimate the strength of the produced fields.Comment: Revtex, 14 pages, 3 figures appended as uuencoded postscript-fil
