Séparation de phase dans un fluide actif scalaire

Résumé

Le cours discute les transitions de phase dans un mélange fluide hors équilibre en suivant un modèle proposé par M. Cates et ses collaborateurs. Il montre comment le mûrissement d'Ostwald peut être inversé et conduire à des phases de gouttes de taille finie.
