The random walk of intermittently self-propelled particles
Agniva Datta, Carsten Beta, Robert GroÃmann
Motivated by various recent experimental findings, we propose a dynamical model of intermittently self-propelled particles: active particles that recurrently switch between two mod…

Deciphering the dual chemotaxis strategy of bacteria in porous media
Sönke Beier, Veronika Pfeifer, Agniva Datta +2
Chemotaxis of bacterial swimmers that move in a run-and-turn pattern is well studied in uniform bulk fluid. It is primarily based on modulating the run time in dependence on the sw…

Intermittent Run Motility of Bacteria in Gels Exhibits Power-Law Distributed Dwell Times
Agniva Datta, Sönke Beier, Veronika Pfeifer +2
While bacterial swimming has been well characterized in uniform liquid environments, only little is known about how bacteria propagate through complex environments, such as gel-lik…
