Tumbling Downhill along a Given Curve
Jean-Pierre Eckmann, Yaroslav I. Sobolev, Tsvi Tlusty
A cylinder will roll down an inclined plane in a straight line. A cone will roll around a circle on that plane and then will stop rolling. We ask the inverse question: For which cu…
Instabilities Appearing in Cosmological Effective Field theories: When and How?
Jean-Pierre Eckmann, Farbod Hassani, Hatem Zaag
Nonlinear partial differential equations appear in many domains of physics, and we study here a typical equation which one finds in effective field theories (EFT) originated from c…
Non-Equilibrium Steady States for Networks of Oscillators
Noé Cuneo, Jean-Pierre Eckmann, Martin Hairer +1
Non-equilibrium steady states for chains of oscillators (masses) connected by harmonic and anharmonic springs and interacting with heat baths at different temperatures have been th…
The Colored Hofstadter Butterfly for the Honeycomb Lattice
Andrea Agazzi, Jean-Pierre Eckmann, Gian Michele Graf
We rely on a recent method for determining edge spectra and we use it to compute the Chern numbers for Hofstadter models on the honeycomb lattice having rational magnetic flux per…
Trees of nuclei and bounds on the number of triangulations of the 3-ball
Pierre Collet, Jean-Pierre Eckmann, Maher Younan
Based on the work of Durhuus-J{ó}nsson and Benedetti-Ziegler, we revisit the question of the number of triangulations of the 3-ball. We introduce a notion of nucleus (a triangulati…
A Model of Heat Conduction
Pierre Collet, Jean-Pierre Eckmann
We define a deterministic ``scattering'' model for heat conduction which is continuous in space, and which has a Boltzmann type flavor, obtained by a closure based on memory loss b…
