Spatial Structures and Giant Number Fluctuations in Models of Active Matter
, 2012 The large scale fluctuations of the ordered state in active matter systems are usually characterised by studying the "giant number fluctuations" of particles in any finite volume, as compared to the expectations from the central limit theorem.

Self-propelled hard disks: implicit alignment and transition to collective motion
New Journal of Physics, 2015 We formulate a model of self-propelled hard disks whose dynamics is governed by mutually coupled vectors for velocity and body orientation. Numerical integration at low densities reveals that the expected transition from isotropic to aligned collective ...

One ring to rule them all: tuning bacteria collective motion via geometric confinement
New Journal of Physics, 2016 Suspensions of swimming bacteria are known to self-organize into turbulent-like flows for sufficiently high density and nutrients concentration. This spectacular example of collective behavior, on which the survival of the colony itself is believed to ...

Emergent smectic order in simple active particle models
New Journal of Physics, 2016 Novel ‘smectic-P’ behavior, in which self-propelled particles form rows and move on average along them, occurs generically within the orientationally ordered phase of simple models that we simulate.
