Collective states of active matter with stochastic reversals: emergent chiral states and spontaneous current switching
Kristian Stølevik Olsen, Luiza Angheluta, Eirik Grude Flekkøy
We study collective dynamical behavior of active particles with topological interactions and directional reversals. Surprising phenomena are shown to emerge as the interaction rela…

Diffusion of active particles with angular velocity reversal
Kristian Stølevik Olsen
Biological and synthetic microswimmers display a wide range of swimming trajectories depending on driving forces and torques. In this paper we consider a simple overdamped model of…

The escape problem for active particles confined to a disc
Kristian Stølevik Olsen, Luiza Angheluta, Eirik Grude Flekkøy
We study the escape problem for interacting, self-propelled particles confined to a disc, where particles can exit through one open slot on the circumference. Within a minimal 2D V…
