Invited Talks

published on , updated on

These talks are given by invited speakers at LIPhy. The intended audience is the whole LIPhy. A large general introduction intended for non-specialist is usually provided.

Typical talk duration is around one hour and includes about 15 mn of questions. The talks are scheduled usually every monday at 2PM. The place is at the conference room, second floor. Access to the lab can be obtained through the secretaries.

    Hydrodynamic Wave-Particle Coupling: Chaos Generated by Non-regular Bounces

    Résumé : Ten years ago, Y. Couder, was studying delayed coalescence of a drop on a vibrated bath. By serendipity he discovered a unique example of macroscopic wave-particle duality: the walkers.
    A droplet deposited on a vertically vibrated bath may, under some conditions, stay in a stable state for which the air layer that separates the drop from the bath is constantly renewed. The droplet never merges with the bath. Under even more restrictive conditions, the waves created by the consecutive impacts of the droplet on the bath interact with the droplet : the droplet is spontaneously propelled. The object compounded of the particle and the waves is called a walker. Scientific debate about the possible analogy between this system and quantum mechanics is still abundant and far from being closed.
    In this talk, I show that the bouncing phase of the droplet in regard to the driving vibration is a crucial parameter for multi-body interactions and chaos generation. At last, I will tell about very first results about the “wavy” potential that rules the interaction between walkers and I will try to show their quantum analog.
