Résumé en anglais

We present and analyze the growth of an isolated droplet generated by a laser-induced local quench in composition in a microemulsion. The growth dynamics realized in a capillary and thus under optical and spatial constraints is studied in the most general frame of the phase separation kinetics in systems belonging to the universality Ising class d=3, n=1. It can be analyzed with two dimensionless reduced variables defined from two characteristic length and time scales of the system. The observed dynamics of these systems are here compared using the same scaled parameters. In the late stage, it appears that the experimental growth behavior in τ1/3 (τ being the reduced time) corresponds to the slowest kinetics mechanism for a droplets assembly as well as for an isolated droplet.< Réduire
