Liquid crystals of hard rectangles on flat and cylindrical manifolds
Christoph E. Sitta, Frank Smallenburg, Raphael Wittkowski +1
Using the classical density functional theory of freezing and Monte Carlo computer simulations, we explore the liquid-crystalline phase behavior of hard rectangles on flat and cyli…
Nonequilibrium dynamics of mixtures of active and passive colloidal particles
Raphael Wittkowski, Joakim Stenhammar, Michael E. Cates
We develop a mesoscopic field theory for the collective nonequilibrium dynamics of multicomponent mixtures of interacting active (i.e., motile) and passive (i.e., nonmotile) colloi…
Helical paths, gravitaxis, and separation phenomena for mass-anisotropic self-propelling colloids: experiment versus theory
Andrew I. Campbell, Raphael Wittkowski, Borge ten Hagen +2
The self-propulsion mechanism of active colloidal particles often generates not only translational but also rotational motion. For particles with an anisotropic mass density under…
