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…
Bicontinuity in active phase separation
Paarth Gulati, Liang Zhao, Michio Tateno +3
We study phase separation between coexisting active and passive fluids in three-dimensions, using numerical simulation and experiments. Chaotic flows of the active phase drive gian…
Asymmetric fluctuations and self-folding of active interfaces
Liang Zhao, Paarth Gulati, Fernando Caballero +4
We study the structure and dynamics of the interface separating a passive fluid from a microtubule-based active fluid. Turbulent-like active flows power giant interfacial fluctuati…
Traveling waves at the surface of active liquid crystals
Paarth Gulati, Fernando Caballero, Itamar Kolvin +2
Active liquid crystals exert nonequilibrium stresses on their surroundings through constant consumption of energy, giving rise to dynamical steady states not present in equilibrium…
