Spinodal Gravitational Waves
Yago Bea, Jorge Casalderrey-Solana, Thanasis Giannakopoulos +5
We uncover a new gravitational-wave production mechanism in cosmological, first-order, thermal phase transitions. These are usually assumed to proceed via the nucleation of bubbles…
Domain Collisions
Yago Bea, Jorge Casalderrey-Solana, Thanasis Giannakopoulos +3
We use holography to study collisions of phase domains formed in a four-dimensional, strongly-coupled gauge theory with a first-order, thermal phase transition. We find three quali…
Bubble Wall Velocity from Holography
Yago Bea, Jorge Casalderrey-Solana, Thanasis Giannakopoulos +3
Cosmological phase transitions proceed via the nucleation of bubbles that subsequently expand and collide. The resulting gravitational wave spectrum depends crucially on the bubble…
