Spontaneous division and motility in active nematic droplets
L. Giomi, A. DeSimone
We investigate the mechanics of an active droplet endowed with internal nematic order and surrounded by an isotropic Newtonian fluid. Using numerical simulations we demonstrate tha…
Softly Constrained Films
Luca Giomi
The shape of materials is often subject to a number of geometric constraints that limit the size of the system or fix the structure of its boundary. In soft and biological material…
Defect annihilation and proliferation in active nematics
Luca Giomi, Mark J. Bowick, Xu Ma +1
Liquid crystals inevitably possess topological defect excitations generated through boundary conditions, applied fields or in quenches to the ordered phase. In equilibrium pairs of…
Swarming, swirling and stasis in sequestered bristle-bots
L. Giomi, N. Hawley-Weld, L. Mahadevan
The collective ability of organisms to move coherently in space and time is ubiquitous in any group of autonomous agents that can move and sense each other and the environment. Her…
