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…
Holographic Evolution with Dynamical Boundary Gravity
Christian Ecker, Wilke van der Schee, David Mateos +1
Holography has provided valuable insights into the time evolution of strongly coupled gauge theories in a fixed spacetime. However, this framework is insufficient if this spacetime…
Multiple Mass Hierarchies from Complex Fixed Point Collisions
Anton F. Faedo, Carlos Hoyos, David Mateos +1
A pair of complex-conjugate fixed points that lie close to the real axis generates a large mass hierarchy in the real renormalization group flow that passes in between them. We sho…
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…
