A statistical physics viewpoint on the dynamics of the bouncing ball
Jean-Yonnel Chastaing, Jean-Christophe Géminard, Eric Bertin
We study from a statistical physics perspective the dynamics of a bouncing ball maintained in a chaotic regime thanks to collisions with a plate experiencing an aperiodic vibration…
Coupling spin to velocity: collective motion of Hamiltonian polar particles
Sigbjørn Løland Bore, Michael Schindler, Khanh-Dang Nguyen Thu Lam +2
We propose a conservative two-dimensional particle model in which particles carry a continuous and classical spin. The model includes standard ferromagnetic interactions between sp…
Symmetry restoration by pricing in a duopoly of perishable goods
Su Do Yi, Seung Ki Baek, Guillaume Chevereau +1
Competition is a main tenet of economics, and the reason is that a perfectly competitive equilibrium is Pareto-efficient in the absence of externalities and public goods. Whether a…
Edwards thermodynamics for a driven athermal system with dry friction
Giacomo Gradenigo, Ezequiel E. Ferrero, Eric Bertin +1
We obtain, using semi-analytical transfer operator techniques, the Edwards thermodynamics of a one-dimensional model of blocks connected by harmonic springs and subjected to dry fr…
Comparison between Smoluchowski and Boltzmann approaches for self-propelled rods
Eric Bertin, Aparna Baskaran, Hugues Chaté +1
Considering systems of self-propelled polar particles with nematic interactions ("rods"), we compare the continuum equations describing the evolution of polar and nematic order par…
On the relevance of disorder in athermal amorphous materials under shear
Elisabeth Agoritsas, Eric Bertin, Kirsten Martens +1
We show that, at least at a mean-field level, the effect of structural disorder in sheared amorphous media is very dissimilar depending on the thermal or athermal nature of their u…
