Bubble Wall Velocity at Strong Coupling
Francesco Bigazzi, Alessio Caddeo, Tommaso Canneti +1
Using the holographic correspondence as a tool, we determine the steady-state velocity of expanding vacuum bubbles nucleated within chiral finite temperature first-order phase tran…
Dark Holograms and Gravitational Waves
Francesco Bigazzi, Alessio Caddeo, Aldo L. Cotrone +1
Spectra of stochastic gravitational waves (GW) generated in cosmological first-order phase transitions are computed within strongly correlated theories with a dual holographic desc…
Fate of false vacua in holographic first-order phase transitions
Francesco Bigazzi, Alessio Caddeo, Aldo L. Cotrone +1
Using the holographic correspondence as a tool, we study the dynamics of first-order phase transitions in strongly coupled gauge theories at finite temperature. Considering an evol…
The Holographic QCD Axion
Francesco Bigazzi, Alessio Caddeo, Aldo L. Cotrone +2
A holographic model of QCD axion is presented. It describes a composite axion in the KSVZ class. Having a gravity dual, based on the Witten-Sakai-Sugimoto model, it is calculable i…
