DESCRIPTION:Speakers: Alessio Caddeo\n\nFirst-order phase transitions invo
 lve rich dynamics\, from bubble nucleation and expansion to spinodal insta
 bilities. Describing these processes requires understanding how an order p
 arameter interacts with the surrounding fluid. In this talk\, I will prese
 nt an improved fluid-scalar effective description of first-order phase tra
 nsitions in relativistic theories and test it against a microscopic calcul
 ation in a holographic model. I will discuss how the spinodal instability 
 is linked to thermodynamic stability. The holographic results confirm the 
 validity of the effective description at long wavelengths and show that it
  improves upon a purely hydrodynamic treatment in most cases.\n \n\nhttps
