The movement of microorganisms is not only an essential aspect of life, it also serves as a
fruitful model for the development of synthetic microswimmers or microrobots with potential …

The survival of many microorganisms, like Leptospira or Spiroplasma bacteria, can depend
on their ability to navigate towards regions of favorable viscosity. While this ability, called …

Gradients in fluid viscosity characterize microbiomes ranging from mucus layers on marine
organisms and human viscera, to biofilms. Although such environments are widely …

From intracellular protein trafficking to large-scale motion of animal groups, the physical
concepts driving the self-organization of living systems are still largely unraveled. Self …

We study the dynamics of a Brownian circle swimmer with a time-dependent self-propulsion
velocity in an external temporally varying harmonic potential. For several situations, the …

Stochastic processes are commonly used models to describe dynamics of a wide variety of
nonequilibrium phenomena ranging from electrical transport to biological motion. The …

Run-and-tumble motion is a prominent locomotion strategy employed by many living
microorganisms. It is characterized by straight swimming intervals (runs), which are …

We study an active matter system comprised of magnetic microswimmers confined in a
microfluidic channel and show that it exhibits a new type of self-organized behavior …

We experimentally and theoretically study the dynamics of a low-Reynolds number helical
swimmer moving across viscosity gradients. Experimentally, a double-layer viscosity is …

The movement of microswimmers is often described by active Brownian particle models.
Here we introduce a variant of these models with several internal states of the swimmer to …
