Ultrasound-propelled nano- and microspinners
Johannes Voß, Raphael Wittkowski
We study nonhelical nano- and microparticles that, through a particular shape, rotate when they are exposed to ultrasound. Employing acoustofluidic computer simulations, we investi…
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…
Collective dynamics and pair-distribution function of active Brownian ellipsoids
Stephan Bröker, Michael te Vrugt, Raphael Wittkowski
While the collective dynamics of spherical active Brownian particles is relatively well understood by now, the much more complex dynamics of nonspherical active particles still rai…
Pair-distribution function of active Brownian spheres in three spatial dimensions: simulation results and analytical representation
Stephan Bröker, Michael te Vrugt, Julian Jeggle +2
The pair-distribution function, which provides information about correlations in a system of interacting particles, is one of the key objects of theoretical soft matter physics. In…
Acoustic propulsion of nano- and microcones: dependence on particle size, acoustic energy density, and sound frequency
Johannes Voß, Raphael Wittkowski
Employing acoustofluidic simulations, we study the propulsion of cone-shaped nano- and microparticles by a traveling ultrasound wave. In particular, we investigate how the acoustic…
Passive and active field theories for disease spreading
Michael te Vrugt, Julian Jeggle, Raphael Wittkowski
The worldwide COVID-19 pandemic has led to a significant growth of interest in the development of mathematical models that allow to describe effects such as social distancing measu…
