Differently Shaped Hard Body Colloids in Confinement: From passive to active particles
Henricus H. Wensink, Hartmut Löwen, Matthieu Marechal +5
We review recent progress in the theoretical description of anisotropic hard colloidal particles. The shapes considered range from rods and dumbbells to rounded cubes, polyhedra an…
Generalized Onsager theory for strongly anisometric patchy colloids
H. H. Wensink, E. Trizac
The implications of soft `patchy' interactions on the orientational disorder-order transition of strongly elongated colloidal rods and flat disks is studied within a simple Onsager…
Capturing self-propelled particles in a moving microwedge
A. Kaiser, K. Popowa, H. H. Wensink +1
Catching fish with a fishing net is typically done either by dragging a fishing net through quiescent water or by placing a stationary basket trap into a stream. We transfer these…
Controlling active self-assembly through broken particle symmetries
H. H. Wensink, V. Kantsler, R. E. Goldstein +1
Many structural properties of conventional passive materials are known to arise from the symmetries of their microscopic constituents. By contrast, it is largely unclear how the in…
Fluid dynamics of bacterial turbulence
Jörn Dunkel, Sebastian Heidenreich, Knut Drescher +3
Self-sustained turbulent structures have been observed in a wide range of living fluids, yet no quantitative theory exists to explain their properties. We report experiments on act…
