Active matter extracts energy from its surroundings at the single particle level and transforms
it into mechanical work. Examples include cytoskeleton biopolymers and bacterial …

Liquid crystals (LCs) are ubiquitous in display technologies. The orientational ordering in the
nematic phase of LCs gives rise to structural anisotropy, the ability to form topological …

Various types of structures self-organised by animals exist in nature, such as bird flocks and
insect swarms, which stem from the local communications of vast numbers of limited …

We study how confinement transforms the chaotic dynamics of bulk microtubule-based
active nematics into regular spatiotemporal patterns. For weak confinements in disks …

Active matter exhibits remarkable collective behaviour in which flows, continuously
generated by active particles, are intertwined with the orientational order of these particles …

Hydrodynamic theories effectively describe many-body systems out of equilibrium in terms of
a few macroscopic parameters. However, such parameters are difficult to determine from …

Filamentous cyanobacteria can show fascinating examples of nonequilibrium self-
organization, which, however, are not well understood from a physical perspective. We …

We perform numerical simulations of isolated, partially active polymers, driven out-of-
equilibrium by a fraction of their monomers. We show that, if the active beads are all …

Active nematics are a class of far-from-equilibrium materials characterized by local
orientational order of force-generating, anisotropic constitutes. Traditional methods for …

In active matter systems, deformable boundaries provide a mechanism to organize internal
active stresses. To study a minimal model of such a system, we perform particle-based …
