Multi-stable free states of an active particle from a coherent memory dynamics
Vincent Bacot, Stéphane Perrard, Matthieu Labousse +2
We investigate the dynamics of a deterministic self-propelled particle endowed with coherent memory. We evidence experimentally and numerically that it exhibits several stable free…
Transition to chaos in wave memory dynamics in a harmonic well : deterministic and noise-driven behaviour
S. Perrard, M. Labousse
A walker is the association of a sub-millimetric bouncing drop moving along with a co-evolving Faraday wave. When confined in a harmonic potential, its stable trajectories are peri…
Tunable bimodal explorations of space from memory-driven deterministic dynamics
Maxime Hubert, Stéphane Perrard, Matthieu Labousse +2
We present a wave-memory driven system that exhibits intermittent switching between two propulsion modes in free space. The model is based on a point-like particle emitting periodi…
Build-up of macroscopic eigenstates in a memory-based constrained system
Matthieu Labousse, Stéphane Perrard, Yves Couder +1
A bouncing drop and its associated accompanying wave forms a walker. Based on previous works, we show in this article that it is possible to formulate a simple theoretical framewor…
