Sperm are highly specialized cells, which have been subject to substantial evolutionary
pressure. Whereas some sperm features are highly conserved, others have undergone …

We perform hydrodynamic simulations using the method of multi-particle collision dynamics
and a theoretical analysis to study a single squirmer microswimmer at high Péclet number …

The migration and rheotaxis of elliptical squirmers (a swimmer self-propels by imposing a
given tangential velocity at its surface) in a Poiseuille flow are simulated numerically. The …

Self-organization of meso-and macroscale structures is a highly active research field that
exploits a wide variety of physicochemical phenomena, including surface tension …

Microswimmers move autonomously but are subject to external fields, which influence their
swimming path and their collective dynamics. With three concrete examples we illustrate …

Dissipative chemical systems hold the potential to enable life‐like behavior in synthetic
matter, such as self‐organization, motility, and dynamic switching between different states …

Biological microswimmers such as bacteria and sperm cells often encounter complex
biological fluid environments. Here we use the well-known squirmer microswimmer model to …

The method of multi-particle collision dynamics (MPCD) and its different implementations
are commonly used in the field of soft matter physics to simulate fluid flow at the micron …

We used a two-dimensional lattice Boltzmann method to simulate the sedimentation motion
of an elliptical squirmer in a vertical channel, taking into account the case of a circular …

Gravity has an unavoidable effect on all living organisms inhabiting fluidic surroundings. To
investigate the spatial distribution of bacteria in quiescent fluids and their rheotactic behavior …
