Susceptibility of Orientationally-Ordered Active Matter to Chirality Disorder
Bruno Ventejou, Hugues Chaté, Raul Montagne +1
We investigate the susceptibility of long-range ordered phases of two-dimensional dry aligning active matter to population disorder, taken in the form of a distribution of intrinsi…
Collective Motion of Self-Propelled Particles with Memory
Ken H. Nagai, Yutaka Sumino, Raul Montagne +2
We show that memory, in the form of underdamped angular dynamics, is a crucial ingredient for the collective properties of self-propelled particles. Using Vicsek-style models with…
Nonlinear dynamics at the interface of two-layer stratified flows over pronounced obstacles
C. Cabeza, J. Varela, I. Bove +6
The flow of a two--layer stratified fluid over an abrupt topographic obstacle, simulating relevant situations in oceanographic problems, is investigated numerically and experimenta…
Minimal model for active nematics: quasi-long-range order and giant fluctuations
Hugues Chate, Francesco Ginelli, Raul Montagne
We propose a minimal microscopic model for active nematic particles similar in spirit to the Vicsek model for self-propelled polar particles. In two dimensions, we show that this m…
Optimized suppression of coherent noise from seismic data using the Karhunen-Loeve transform
Raul Montagne, Giovani L. Vasconcelos
Signals obtained in land seismic surveys are usually contaminated with coherent noise, among which the ground roll (Rayleigh surface waves) is of major concern for it can severely…
Complex dynamics in a one--block model for earthquakes
Raul Montagne, G. L. Vasconcelos
A two-dimensional earthquake model that consists of a single block resting upon a slowly moving rough surface and connected by two springs to rigid supports is studied. Depending o…
