Controlling Turbulent Flows in Compressible Active Nematics
Dimitrios Krommydas, Paarth Gulati, Aparna Baskaran +1
Motivated by experiments on light-patterned, quasi-2D active suspensions that exhibit large density variations, we develop a continuum theory of compressible active nematics--suspe…
Segregation dynamics in active-passive mixtures of semiflexible filaments
Chitrak Bhowmik, Aparna Baskaran, Sriram Ramaswamy
We study the segregation of motile semiflexible filaments from a background of similar but non-motile filaments. Our Langevin dynamics simulations reveal a wide range of emergent s…
Coarsening of biomimetic condensates in a self-stirring active fluid
Jeremy Laprade, Layne Frechette, Christopher Amey +4
Coarsening, the process where larger structures grow at the expense of smaller ones, is a fundamental aspect of multiphase systems. The cell cytoplasm exemplifies an out-of-equilib…
The mechanics of disclination emergence in 3D active nematics
Yingyou Ma, Christopher Amey, Aparna Baskaran +1
The spontaneous creation of disclinations is a defining characteristic of active nematics, which is rarely observed in equilibrium systems or other active matter systems. Thus, und…
Active noise-induced dynamic clustering of passive colloids
Layne B. Frechette, Aparna Baskaran, Michael F. Hagan
Active fluids generate spontaneous, often chaotic mesoscale flows. Harnessing these flows to drive embedded soft materials into structures with controlled length scales and lifetim…
