Posture selection in active elastic filaments
Adam Pearl, Ludwig A. Hoffmann, L. Mahadevan
Posture control in slender bodies such as snakes and eels arises from the interplay between passive deformation, active internal actuation, and task-level constraints. We formulate…
How to grow a straight filament
Ludwig A. Hoffmann, L. Mahadevan
How can a growing biological filament remain straight despite stochastic fluctuations in growth? Motivated by filamentary structures that develop reproducibly across biological sys…
Designing highly efficient lock-and-key interactions in anisotropic active particles
Solenn Riedel, Ludwig A. Hoffmann, Luca Giomi +1
Cluster formation of microscopic swimmers is key to the formation of biofilms and colonies, efficient motion and nutrient uptake, but, in the absence of other interactions, require…
Topology-driven ordering of flocking matter
Amélie Chardac, Ludwig A. Hoffmann, Yoann Poupart +2
When interacting motile units self-organize into flocks, they realize one of the most robust ordered state found in nature. However, after twenty five years of intense research, th…
Chiral stresses in nematic cell monolayers
Ludwig A. Hoffmann, Koen Schakenraad, Roeland M. H. Merks +1
Recent experiments on monolayers of spindle-like cells plated on adhesive stripe-shaped domains have provided a convincing demonstration that certain types of collective phenomena…
