Parametric resonance in a conservative system of coupled nonlinear oscillators
Johann Maddi, Christophe Coste, Michel Saint Jean
We study a conservative system of two nonlinear coupled oscillators. The eigenmodes of the system are thus nonlinearly coupled, and one of them may induce a parametric amplificatio…
Single File Diffusion of particles with long ranged interactions: damping and finite size effects
Jean-Baptiste Delfau, Christophe Coste, Michel Saint-Jean
We study the Single File Diffusion (SFD) of a cyclic chain of particles that cannot cross each other, in a thermal bath, with long ranged interactions, and arbitrary damping. We pr…
Single file diffusion of macroscopic charged particles
Christophe Coste, Jean-Baptiste Delfau, Catherine Even +1
In this paper, we study a macroscopic system of electrically interacting metallic beads organized as a sequence along an annulus. A random mechanical shaking mimics the thermal exc…
Scattering of dislocated wavefronts by vertical vorticity and the Aharonov-Bohm effect II: Dispersive waves
Christophe Coste, Fernando Lund
Previous results on the scattering of surface waves by vertical vorticity on shallow water are generalized to the case of dispersive water waves. Dispersion effects are treated per…
Scattering of dislocated wavefronts by vertical vorticity and the Aharonov-Bohm effect I: Shallow water
Christophe Coste, Makoto Umeki, Fernando Lund
When a surface wave interacts with a vertical vortex in shallow water the latter induces a dislocation in the incident wavefronts that is analogous to what happens in the Aharonov-…
Scattering of first and second sound waves by quantum vorticity in superfluid Helium
C. Coste, F. Lund
We study the scattering of first and second sound waves by quantum vorticity in superfluid Helium using two-fluid hydrodynamics. The vorticity of the superfluid component and the s…
