Parametric resonance in a conservative system of coupled nonlinear oscillators

Autor: 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 amplification of the other, called an autoparametric resonance of the system. The

International audience; We describe the transport of a finite chain of [Formula: see text] identical particles in a thermal bath, through thin channels that forbid any crossing with a conceptually and technically simple method, that is neither restri

The Contact Dynamics method: A nonsmooth story

Autor: Frédéric Dubois, Michel Saint Jean, Vincent Acary

Publikováno v: Comptes Rendus Mécanique. 346:247-262

When velocity jumps are occurring, the dynamics is said to be nonsmooth. For instance, in collections of contacting rigid bodies, jumps are caused by shocks and dry friction. Without compliance at the interface, contact laws are not only non-differen

Transverse single-file diffusion and enhanced longitudinal diffusion near a subcritical bifurcation

Autor: Michel Saint Jean, Tommy Dessup, Christophe Coste

Publikováno v: Physical review. E. 97(5-1)

A quasi-one-dimensional system of repelling particles undergoes a configurational phase transition when the transverse confining potential decreases. Below a threshold, it becomes energetically favorable for the system to adopt one of two staggered r

Enhancement of Brownian motion for a chain of particles in a periodic potential

Autor: Michel Saint Jean, Tommy Dessup, Christophe Coste

Publikováno v: Physical Review E
Physical Review E, American Physical Society (APS), 2018, 97, ⟨10.1103/PhysRevE.97.022103⟩

International audience; The transport of particles in very confined channels in which single file diffusion occurs has been largely studied in systems where the transverse confining potential is smooth. However, in actual physical systems, this poten

Longitudinal and Transverse Single File Diffusion in Quasi-1D Systems

Autor: Jean-Baptiste Delfau, Michel Saint Jean, Christophe Coste

Publikováno v: Biophysical Reviews and Letters. :333-348

We review our recent results on Single File Diffusion (SFD) of a chain of particles that cannot cross each other, in a thermal bath, with long ranged interactions, and arbitrary damping. We exhibit new behaviors specifically associated to small syste

Interaction, coalescence, and collapse of localized patterns in a quasi-one-dimensional system of interacting particles

Autor: Tommy Dessup, Michel Saint Jean, Christophe Coste

Publikováno v: Physical review. E. 95(1-1)

We study the path toward equilibrium of pairs of solitary wave envelopes (bubbles) that modulate a regular zigzag pattern in an annular channel. We evidence that bubble pairs are metastable states, which spontaneously evolve toward a stable single bu

Physical Review E, American Physical Society (APS), 2016, 94, pp.12217-12217. ⟨10.1103/PhysRevE.94.012217⟩

International audience; We study the dynamics of localized nonlinear patterns in a quasi-one-dimensional many-particle system near a subcritical pitchfork bifurcation. The normal form at the bifurcation is given and we show that these patterns can be
