Magnetic field generation from bubble collisions during first-order phase transition
Jing Yang, Ligong Bian
Abstract
We study the magnetic field generation from the cosmological first-order electroweak phase transition. We calculate the magnetic fields induced by the variation of the Higgs phase for two-bubble and three-bubble collisions, and find that the generated magnetic field strength with the effect of bubble shape distortion is about half of that derived without including the shape deformation. Our study shows that electromagnetic currents in the collision direction produce the ringlike magnetic field in the intersection area of colliding bubbles, which has a chance to seed the primordial magnetic field constrained by intergalactic magnetic field observations.
