Thermotaxis of Janus Particles
Sven Auschra, Andreas Bregulla, Klaus Kroy +1
The interactions of autonomous microswimmers play an important role for the formation of collective states of motile active matter. We study them in detail for the common microswim…
Coarse Graining Nonisothermal Microswimmer Suspensions
Sven Auschra, Dipanjan Chakraborty, Gianmaria Falasco +2
We investigate coarse-grained models of suspended self-thermophoretic microswimmers. Upon heating, the Janus spheres, with hemispheres made of different materials, induce a heterog…
Density and Polarization of Active Brownian Particles in Curved Activity Landscapes
Sven Auschra, Viktor Holubec
Suspensions of motile active particles with space dependent activity form characteristic polarization and density patterns. Recent single-particle studies for planar activity lands…
Polarization-Density Patterns of Active Particles in Motility Gradients
Sven Auschra, Viktor Holubec, Nicola Andreas Söker +2
The co-localization of density modulations and particle polarization is a characteristic emergent feature of motile active matter in activity gradients. It can therefore play the r…
Active-Particle Polarization Without Alignment Forces
Nicola Andreas Söker, Sven Auschra, Viktor Holubec +2
Active-particle suspensions exhibit distinct polarization-density patterns in activity landscapes, even without anisotropic particle interactions. Such polarization without alignme…
