Scalar field theory for active-particle phase separation
Raphael Wittkowski, Adriano Tiribocchi, Joakim Stenhammar +3
Recent theories predict phase separation among orientationally disordered active particles whose propulsion speed decreases rapidly enough with density. Coarse-grained models of th…
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…
Dynamics of a deformable active particle under shear flow
Mitsusuke Tarama, Andreas M. Menzel, Borge ten Hagen +3
The motion of a deformable active particle in linear shear flow is explored theoretically. Based on symmetry considerations, in two spatial dimensions, we propose coupled nonlinear…
Brownian motion and the hydrodynamic friction tensor for colloidal particles of complex shape
Daniela J. Kraft, Raphael Wittkowski, Borge ten Hagen +3
We synthesize colloidal particles with various anisotropic shapes and track their orientationally resolved Brownian trajectories using confocal microscopy. An analysis of appropria…
Circular motion of asymmetric self-propelling particles
Felix Kümmel, Borge ten Hagen, Raphael Wittkowski +5
Micron-sized self-propelled (active) particles can be considered as model systems for characterizing more complex biological organisms like swimming bacteria or motile cells. We pr…
Structure and dynamics of interfaces between two coexisting liquid crystalline phases
Simon Praetorius, Axel Voigt, Raphael Wittkowski +1
The phase-field-crystal model is used to access the structure and thermodynamics of interfaces between two coexisting liquid crystalline phases in two spatial dimensions. Depending…
