Soft repulsive mixtures under gravity: brazil-nut effect, depletion bubbles, boundary layering, nonequilibrium shaking
Tobias Kruppa, Tim Neuhaus, René Messina +1
A binary mixture of particles interacting via long-ranged repulsive forces is studied in gravity by computer simulation and theory. The more repulsive A-particles create a depletio…

Chemotactic predator-prey dynamics
Ankush Sengupta, Tobias Kruppa, Hartmut Löwen
A discrete chemotactic predator-prey model is proposed in which the prey secrets a diffusing chemical which is sensed by the predator and vice versa. Two dynamical states correspon…
