Geometric criteria for the absence of effective many-body interactions in nonadditive hard particle mixtures
René Wittmann, Sabine Jansen, Hartmut Löwen
We consider a mixture of small and big classical particles in arbitrary spatial dimensions interacting via hard-body potentials with non-additive excluded-volume interactions. In p…
Active Colloids in Harmonic Optical Potentials
Ivo Buttinoni, Lorenzo Caprini, Laura Alvarez +2
We study the motion of active patchy colloids in an optical trap using experiments, theory and numerical simulations. To achieve isotropic and harmonic confinement, we prototype mi…
Active particles driven by competing spatially dependent self-propulsion and external force
Lorenzo Caprini, Umberto Marini Bettolo Marconi, René Wittmann +1
We investigate how the competing presence of a nonuniform motility landscape and an external confining field affects the properties of active particles. We employ the active Ornste…
