Spontaneous flows and dynamics of full-integer topological defects in polar active matter
Jonas Rønning, Julian Renaud, Amin Doostmohammadi +1
Polar active matter of self-propelled particles sustain spontaneous flows through the full-integer topological defects. We study theoretically the effect of both polar and dipolar…

Defect self-propulsion in active nematic films with spatially-varying activity
Jonas Rønning, M. Cristina Marchetti, Luiza Angheluta
We study the dynamics of topological defects in active nematic films with spatially-varying activity and consider two setups: i) a constant activity gradient, and ii) a sharp jump…

Trapping of active Brownian and run-and-tumble particles: a first-passage time approach
Emily Qing Zang Moen, Kristian Stølevik Olsen, Jonas Rønning +1
We use a first-passage time approach to study the statistics of the trapping times induced by persistent motion of active particles colliding with flat boundaries. The angular firs…
