Second sound resonators and tweezers as vorticity or velocity probes : fabrication, model and method
Eric Woillez, Jérôme Valentin, Philippe-E. Roche
An analytical model of open-cavity second sound resonators is presented and validated against simulations and experiments in superfluid helium using a new resonator design that ach…
Local measurement of vortex statistics in quantum turbulence
Eric Woillez, Jérôme Valentin, Philippe-E Roche
The density fluctuations of quantum vortex lines are measured in a turbulent flow of superfluid He, at temperatures corresponding to superfluid fraction of 16%, 47% and 81%. The pr…
Nonlocal stationary probability distributions and escape rates for an active Ornstein-Uhlenbeck particle
Eric Woillez, Yariv Kafri, Vivien Lecomte
We evaluate the steady-state distribution and escape rate for an Active Ornstein-Uhlenbeck Particle (AOUP) using methods from the theory of large deviations. The calculation is car…
Instantons for the destabilization of the inner Solar System
Eric Woillez, Freddy Bouchet
For rare events, path probabilities often concentrate close to a predictable path, called instanton. First developed in statistical physics and field theory, instantons are action…
The active trap model
Eric Woillez, Yariv Kafri, Nir Gov
Motivated by the dynamics of particles embedded in active gels, both in-vitro and inside the cytoskeleton of living cells, we study an active generalization of the classical trap m…
Ramifications of disorder on active particles in one dimension
Ydan Ben Dor, Eric Woillez, Yariv Kafri +2
The effects of quenched disorder on a single and many active run-and-tumble particles is studied in one dimension. For a single particle, we consider both the steady-state distribu…
