Binary Mixtures of Intelligent Active Brownian Particles with Visual Perception
Rajendra Singh Negi, Roland G. Winkler, Gerhard Gompper
The collective properties of a binary mixture of A- and B-type self-steering particles endowed with visual perception are studied by computer simulations. Active Brownian particles…
Chiral active systems near a substrate: Emergent damping length controlled by fluid friction
Joscha Mecke, Yongxiang Gao, Gerhard Gompper +1
Chiral active fluids show the emergence of a turbulent behavior characterized by multiple dynamic vortices whose maximum size is specific for each experimental system. This is in c…
Alignment-Induced Self-Organization of Autonomously Steering Microswimmers: Turbulence, Vortices, and Jets
Segun Goh, Elmar Westphal, Roland G. Winkler +1
Systems of motile microorganisms exhibit a multitude of collective phenomena, including motility-induced phase separation and turbulence. Sensing of the environment and adaptation…
HTMPC: A heavily templated C++ library for large scale particle-based mesoscale hydrodynamics simulations using multiparticle collision dynamics
Elmar Westphal, Segun Goh, Roland G. Winkler +1
We present HTMPC, a Heavily Templated C++ library for large-scale simulations implementing multi-particle collision dynamics (MPC), a particle-based mesoscale hydrodynamic simulati…
Interacting Streams of Cognitive Active Agents in a Three-Way Intersection
Priyanka Iyer, Rajendra Singh Negi, Andreas Schadschneider +1
The emergent collective motion of active agents - in particular pedestrians - at a three-way intersection is studied by Langevin simulations of cognitive intelligent active Brownia…
Swirling due to misaligned perception-dependent motility
Rodrigo Saavedra, Gerhard Gompper, Marisol Ripoll
A system of particles with motility variable in terms of a vision-type of perception is here investigated by a combination of Langevin dynamics simulations in two-dimensional syste…
