Nonequilibrium clustering of self-propelled rods

F Peruani, A Deutsch, M Bär - Physical Review E, 2006 - APS
Motivated by aggregation phenomena in gliding bacteria, we study collective motion in a two-dimensional
model of active, self-propelled rods interacting through volume exclusion. In …

Modeling collective motion: variations on the Vicsek model

H Chaté, F Ginelli, G Grégoire, F Peruani… - The European Physical …, 2008 - Springer
We argue that the model introduced by Vicsek et al. in which self-propelled particles align
locally with neighbors is, because of its simplicity, central to most studies of collective motion …

Collective motion and nonequilibrium cluster formation in colonies of gliding bacteria

F Peruani, J Starruß, V Jakovljevic… - Physical review …, 2012 - APS
We characterize cell motion in experiments and show that the transition to collective motion
in colonies of gliding bacterial cells confined to a monolayer appears through the …

A mean-field theory for self-propelled particles interacting by velocity alignment mechanisms

F Peruani, A Deutsch, M Bär - The European Physical Journal Special …, 2008 - Springer
A mean-field approach (MFA) is proposed for the analysis of orientational order in a two-dimensional
system of stochastic self-propelled particles interacting by local velocity alignment …

Self-propelled particles with fluctuating speed and direction of motion in two dimensions

F Peruani, LG Morelli - Physical review letters, 2007 - APS
We study general aspects of active motion with fluctuations in the speed and the direction of
motion in two dimensions. We consider the case in which fluctuations in the speed are not …

Large-scale collective properties of self-propelled rods

F Ginelli, F Peruani, M Bär, H Chaté - Physical review letters, 2010 - APS
We study, in two space dimensions, the collective properties of constant-speed polar point
particles interacting locally by nematic alignment in the presence of noise. This minimal …

[HTML][HTML] The 2020 motile active matter roadmap

…, T Speck, A Solon, C Nardini, F Peruani… - Journal of Physics …, 2020 - iopscience.iop.org
Activity and autonomous motion are fundamental in living and engineering systems. This
has stimulated the new field of'active matter'in recent years, which focuses on the physical …

[HTML][HTML] Emergent vortices in populations of colloidal rollers

…, V Chikkadi, K Shitara, O Chepizhko, F Peruani… - Nature …, 2015 - nature.com
Coherent vortical motion has been reported in a wide variety of populations including living
organisms (bacteria, fishes, human crowds) and synthetic active matter (shaken grains, …

Diffusion, subdiffusion, and trapping of active particles in heterogeneous media

O Chepizhko, F Peruani - Physical review letters, 2013 - APS
We study the transport properties of a system of active particles moving at constant speed in
a heterogeneous two-dimensional space. The spatial heterogeneity is modeled by a …

Self-propelled rods: Insights and perspectives for active matter

…, S Heidenreich, F Peruani - Annual Review of …, 2020 - annualreviews.org
A wide range of experimental systems including gliding, swarming and swimming bacteria,
in vitro motility assays, and shaken granular media are commonly described as self-…
