Active Brownian motion with memory delay induced by a viscoelastic medium
Alexander R. Sprenger, Christian Bair, Hartmut Löwen
By now active Brownian motion is a well-established model to describe the motion of mesoscopic self-propelled particles in a Newtonian fluid. On the basis of the generalized Langev…
The Parental Active Model: a unifying stochastic description of self-propulsion
Lorenzo Caprini, Alexander Ralf Sprenger, Hartmut Löwen +1
We propose a new overarching model for self-propelled particles that flexibly generates a full family of "descendants". The general dynamics introduced in this paper, which we deno…
Steady azimuthal flow field induced by a rotating sphere near a rigid disk or inside a gap between two coaxially positioned rigid disks
Abdallah Daddi-Moussa-Ider, Alexander R. Sprenger, Thomas Richter +2
Geometric confinements play an important role in many physical and biological processes and significantly affect the rheology and behavior of colloidal suspensions at low Reynolds…
Time-dependent inertia of self-propelled particles: the Langevin rocket
Alexander R. Sprenger, Soudeh Jahanshahi, Alexei V. Ivlev +1
Many self-propelled objects are large enough to exhibit inertial effects but still suffer from environmental fluctuations. The corresponding basic equations of motion are governed…
Axisymmetric Stokes flow due to a point-force singularity acting between two coaxially positioned rigid no-slip disks
Abdallah Daddi-Moussa-Ider, Alexander Sprenger, Yacine Amarouchene +5
We investigate theoretically on the basis of the steady Stokes equations for a viscous incompressible fluid the flow induced by a Stokeslet located on the centre axis of two coaxia…
Towards an analytical description of active microswimmers in clean and in surfactant-covered drops
Alexander R. Sprenger, Vaseem A. Shaik, Arezoo M. Ardekani +6
Geometric confinements are frequently encountered in the biological world and strongly affect the stability, topology, and transport properties of active suspensions in viscous flo…
