Velocity and Speed Correlations in Hamiltonian Flocks
Mathias Casiulis, Marco Tarzia, Leticia F. Cugliandolo +1
We study a Hamiltonian fluid made of particles carrying spins coupled to their velocities. At low temperatures and intermediate densities, this conservative system exhibits ph…
Bath-Mediated Interactions between Driven Tracers in Dense Single-Files
Alexis Poncet, Olivier Bénichou, Vincent Démery +1
Single-file transport, where particles cannot bypass each other, has been observed in various experimental setups. In such systems, the behaviour of a tracer particle (TP) is subdi…
Attractive versus truncated repulsive supercooled liquids: The dynamics is encoded in the pair correlation function
François P. Landes, Giulio Biroli, Olivier Dauchot +2
We compare glassy dynamics in two liquids that differ in the form of their interaction potentials. Both systems have the same repulsive interactions but one has also an attractive…
Many-body Chaos in Thermalised Fluids
Sugan D. Murugan, Dheeraj Kumar, Subhro Bhattacharjee +1
Linking thermodynamic variables like temperature and the measure of chaos, the Lyapunov exponents , is a question of fundamental importance in many-body systems. By using no…
Order by disorder: saving collective motion from topological defects in a conservative model
Mathias Casiulis, Marco Tarzia, Leticia F. Cugliandolo +1
Using analytic and numerical methods, we study a Hamiltonian model of interacting particles carrying ferro-magnetically coupled continuous spins which are also locally coupled…
