Description
First order phase transitions in superheated systems could be
relevant in cosmological contexts and in neutron star mergers. I will
discuss the bubble dynamics in a chiral symmetry restoring superheated
transition in the Witten-Sakai-Sugimoto holographic model. I will show
how to estimate the bubble nucleation rate and the bubble terminal
velocity at zero chemical potential, and conclude with some results
about the finite chemical potential case.
