Inertial self-propelled particles in anisotropic environments
Alexander R. Sprenger, Christian Scholz, Anton Ldov +2
Self-propelled particles in anisotropic environments can exhibit a motility that depends on their orientation. This dependence is relevant for a plethora of living organisms but di…
Dynamics of active particles with translational and rotational inertia
Alexander R. Sprenger, Lorenzo Caprini, Hartmut Löwen +1
Inertial effects affecting both the translational and rotational dynamics are inherent to a broad range of active systems at the macroscopic scale. Thus, there is a pivotal need fo…
Log it: How to fit an active Brownian particle's mean squared displacement with improved parameter estimation
Maximilian Bailey, Alexander Sprenger, Fabio Grillo +2
The active Brownian particle (ABP) model is widely used to describe the dynamics of active matter systems, such as Janus microswimmers. In particular, the analytical expression for…
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…
Active Brownian motion with orientation-dependent motility: theory and experiments
Alexander R. Sprenger, Miguel Angel Fernandez-Rodriguez, Laura Alvarez +3
Combining experiments on active colloids, whose propulsion velocity can be controlled via a feedback loop, and theory of active Brownian motion, we explore the dynamics of an overd…
