How to derive a predictive active field theory: a step-by-step tutorial
Michael te Vrugt, Jens Bickmann, Raphael Wittkowski
The study of active soft matter has developed into one of the most rapidly growing areas of physics. Field theories, which can be developed either via phenomenological consideratio…
Orientation-dependent propulsion of active Brownian spheres: from self-advection to programmable cluster shapes
Stephan Bröker, Jens Bickmann, Michael te Vrugt +2
Applications of active particles require a method for controlling their dynamics. While this is typically achieved via direct interventions, indirect interventions based, e.g., on…
Active Brownian particles in external force fields: field-theoretical models, generalized barometric law, and programmable density patterns
Jens Bickmann, Stephan Bröker, Raphael Wittkowski
We investigate the influence of external forces on the collective dynamics of interacting active Brownian particles in two as well as three spatial dimensions. Via explicit coarse…
Analytical approach to chiral active systems: suppressed phase separation of interacting Brownian circle swimmers
Jens Bickmann, Stephan Bröker, Julian Jeggle +1
We consider chirality in active systems by exemplarily studying the phase behavior of planar systems of interacting Brownian circle swimmers with a spherical shape. Continuing prev…
Containing a pandemic: Nonpharmaceutical interventions and the "second wave"
Michael te Vrugt, Jens Bickmann, Raphael Wittkowski
In response to the worldwide outbreak of the coronavirus disease COVID-19, a variety of nonpharmaceutical interventions such as face masks and social distancing have been implement…
Collective dynamics of active Brownian particles in three spatial dimensions: a predictive field theory
Jens Bickmann, Raphael Wittkowski
We investigate the nonequilibrium dynamics of spherical active Brownian particles in three spatial dimensions that interact via a pair potential. The investigation is based on a pr…
