Cosmological Bubbles and Solitons: A Classic(al) Effect – Tom Giblin

Cosmological bubble collisions arising from first order phase transitions are a generic consequence of the Eternal Inflation scenario. I will present our computational strategy for generating and evolving these bubbles in 3+1 dimensions and in a self-consistently expanding background. I will show the existence of classical field transitions–the classical nucleation of bubbles during collisions–which can dramatically alter the canonical description of eternal inflation.
