Swimmer suspensions on substrates: anomalous stability and long-range order
Ananyo Maitra, Pragya Srivastava, M. Cristina Marchetti +2
We present a comprehensive theory of the dynamics and fluctuations of a two-dimensional suspension of polar active particles in an incompressible fluid confined to a substrate. We…
Stability from activity
Ananyo Maitra, Pragya Srivastava, M. Cristina Marchetti +3
Suspensions of actively driven anisotropic objects exhibit distinctively nonequilibrium behaviors, and current theories predict that they are incapable of sustaining orientational…
Negative stiffness and modulated states in active nematics
Pragya Srivastava, Prashant Mishra, M. Cristina Marchetti
We examine the dynamics of a compressible active nematic liquid crystal on a frictional substrate. When frictional damping dominates over viscous dissipation, we eliminate flow in…
Patterning of polar active filaments on a tense cylindrical membrane
Pragya Srivastava, Roie Shlomovitz, Nir S. Gov +1
We study the dynamics and patterning of polar contractile filaments on the surface of a cylindrical cell using active hydrodynamic equations that incorporate couplings between curv…
