DOI: 10.1021/acsanm.4c02020

Abstract: Surface-bound molecular motors can drive the collective motion of cytoskeletal filaments in the form of nematic bands and polar flocks in reconstituted gliding assays. Although these “swarming transitions” are an emergent property of active filament… read more here.

DOI: 10.1038/s41467-021-27310-8

Abstract: In active matter systems, deformable boundaries provide a mechanism to organize internal active stresses. To study a minimal model of such a system, we perform particle-based simulations of an elastic vesicle containing a collection of… read more here.

DOI: 10.1088/1367-2630/ab5c70

Abstract: Self-propulsion and navigation due to the sensing of environmental conditions - such as durotaxis and chemotaxis - are remarkable properties of biological cells that cannot be reproduced by single-component self-propelled particles. We introduce and study… read more here.

DOI: 10.1103/physreve.103.013005

Abstract: Initially straight slender elastic filaments or rods with constrained ends buckle and form stable two-dimensional shapes when prestressed by bringing the ends together. Beyond a critical value of this prestress, rods can also deform off… read more here.
