Self-propelled hard disks: implicit alignment and transition to collective motion
Khanh-Dang Nguyen Thu Lam, Michael Schindler, Olivier Dauchot
We show that low density homogeneous phases of self propelled hard disks exhibit a transition from isotropic to polar collective motion, albeit of a qualitatively distinct class fr…
Polar active liquids: a universal classification rooted in nonconservation of momentum
Khanh-Dang Nguyen Thu Lam, Michael Schindler, Olivier Dauchot
We study the spatially homogeneous phases of polar active particles in the low density limit, and specifically the transition from the isotropic phase to collective polar motion. W…
Stochastic perturbation of integrable systems: a window to weakly chaotic systems
Khanh-Dang Nguyen Thu Lam, Jorge Kurchan
Integrable non-linear Hamiltonian systems perturbed by additive noise develop a Lyapunov instability, and are hence chaotic, for any amplitude of the perturbation. This phenomenon…
Large deviations of Lyapunov exponents
Tanguy Laffargue, Khanh-Dang Nguyen Thu Lam, Jorge Kurchan +1
Generic dynamical systems have `typical' Lyapunov exponents, measuring the sensitivity to small perturbations of almost all trajectories. A generic system has also trajectories wit…
