Dynamics of active particles with space-dependent swim velocity
Lorenzo Caprini, Umberto Marini Bettolo Marconi, René Wittmann +1
We study the dynamical properties of an active particle subject to a swimming speed explicitly depending on the particle position. The oscillating spatial profile of the swim veloc…
Topology of orientational defects in confined smectic liquid crystals
Paul A. Monderkamp, René Wittmann, Louis B. G. Cortes +3
We propose a general formalism to characterize orientational frustration of smectic liquid crystals in confinement by interpreting the emerging networks of grain boundaries as obje…
Active Ornstein-Uhlenbeck model for self-propelled particles with inertia
G. H. Philipp Nguyen, René Wittmann, Hartmut Löwen
Self-propelled particles, which convert energy into mechanical motion, exhibit inertia if they have a macroscopic size or move inside a gaseous medium, in contrast to micron-sized…
Particle-resolved topological defects of smectic colloidal liquid crystals in extreme confinement
René Wittmann, Louis B. G. Cortes, Hartmut Löwen +1
Confined samples of liquid crystals are characterized by a variety of topological defects and can be exposed to external constraints such as extreme confinements with nontrivial to…
