Magnetic Fields from Bubble Collisions - A Progress Report
Abstract
Description
Primordial magnetic fields may be created in collisions of expanding bubbles in a first-order cosmological phase transition and later serve as seed fields for galactic magnetic fields. Here I present results from numerical and analytical studies of U(1) bubble collisions done in collaboration with Ed Copeland and Paul Saffin. I also reveal preliminary results from analytical studies of SU(2)xU(1) bubble collisions, which provide first evidence that magnetic fields are created in electroweak two-bubble collisions.
