Hydrodynamics of Micro-swimmers in Films
Arnold J. T. M. Mathijssen, Amin Doostmohammadi, Julia M. Yeomans +1
One of the principal mechanisms by which surfaces and interfaces affect microbial life is by perturbing the hydrodynamic flows generated by swimming. By summing a recursive series…
Intrinsic Free Energy in Active Nematics
Sumesh P. Thampi, Amin Doostmohammadi, Ramin Golestanian +1
Basing our arguments on the theory of active liquid crystals, we demonstrate both analytically and numerically, that the activity can induce an effective free energy which enhances…
Cell division: a source of active stress in cellular monolayers
Amin Doostmohammadi, Sumesh P. Thampi, Thuan B. Saw +3
We introduce the notion of cell division-induced activity and show that the cell division generates extensile forces and drives dynamical patterns in cell assemblies. Extending the…
Upstream swimming in microbiological flows
Arnold J. T. M. Mathijssen, Tyler N. Shendruk, Julia M. Yeomans +1
Interactions between microorganisms and their complex flowing environments are essential in many biological systems. We develop a model for microswimmer dynamics in non-Newtonian P…
Stabilization of active matter by flow-vortex lattices and defect ordering
Amin Doostmohammadi, Michael F. Adamer, Sumesh P. Thampi +1
Active systems, from bacterial suspensions to cellular monolayers, are continuously driven out of equilibrium by local injection of energy from their constituent elements and exhib…
