Turbulent gravitational wakes
Giulio Taiocchi, Christiana Pantelidou, Miguel Zilhão
We construct turbulent gravitational wakes in asymptotically AdS spacetimes by solving the full non-linear Einstein equations in the characteristic formulation. Specifically, w…
Bubble dynamics in a QCD-like phase diagram
Yago Bea, Mauro Giliberti, David Mateos +3
A line of first-order phase transitions is conjectured in the phase diagram of Quantum Chromodynamics at non-zero baryon density. If this is the case, numerical simulations of neut…
Holographic Bubbles with Jecco: Expanding, Collapsing and Critical
Yago Bea, Jorge Casalderrey-Solana, Thanasis Giannakopoulos +4
Cosmological phase transitions can proceed via the nucleation of bubbles that subsequently expand and collide. The resulting gravitational wave spectrum depends crucially on the pr…
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…
