Active flows drive anchoring of nematics at rigid walls
Michael Fang, Ioannis Hadjifrangiskou, Sumesh P. Thampi +2
Although confinement strongly influences flows in active materials, it remains unclear how active particles align at rigid boundaries when no thermodynamic anchoring is imposed. We…
Shear-Induced Collective Shape Oscillations in Dense Soft Suspensions
Ioannis Hadjifrangiskou, Rahil N. Valani, Diogo E. P. Pinto
Dense suspensions of deformable particles can exhibit rich nonequilibrium dynamics arising from complex flow-structure coupling. Using a multi-phase field model, we show that stead…
Channel flows of deformable nematics
Ioannis Hadjifrangiskou, Sumesh P. Thampi, Julia M. Yeomans
We describe channel flows in a continuum model of deformable nematic particles. In a simple shear flow, deformability leads to a nonlinear coupling of strain rate and vorticity, an…
Nematic order from phase synchronization of shape oscillations
Ioannis Hadjifrangiskou, Sumesh P. Thampi, Rahil N. Valani
We show that a suspension of non-interacting deformable particles subjected to an oscillatory shear flow leads to development of nematic order that arises from the phenomenon of ph…
