Emergent Synchronization and Flocking in Purely Repulsive Self-Navigating Particles
Mathias Casiulis, Dov Levine
Inspired by groups of animals and robots, we study the collective dynamics of large numbers of active particles, each one trying to get to its own randomly placed target, while avo…
Self-propulsion and self-navigation: Activity is a precursor to jamming
Mathias Casiulis, Daniel Hexner, Dov Levine
Traffic jams are an everyday hindrance to transport, and typically arise when many vehicles have the same or a similar destination. We show, however, that even when uniformly distr…
Reply to "Comment on "Velocity and Speed Correlations in Hamiltonian Flocks"
Mathias Casiulis, Marco Tarzia, Leticia F. Cugliandolo +1
In their comment on our work (ArXiv:1912.07056v1), Cavagna \textit{et al.} raise several interesting points on the phenomenology of flocks of birds, and conduct additional data ana…
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…
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…
Ferromagnetism-induced Phase Separation in a Two-dimensional Spin Fluid
Mathias Casiulis, Marco Tarzia, Leticia F. Cugliandolo +1
We study the liquid-gas phase separation observed in a system of repulsive particles dressed with ferromagnetically aligning spins, a so-called `spin fluid'. Microcanonical ensembl…
