Live Soap: Stability, Order, and Fluctuations in Apolar Active Smectics
Live Soap: Stability, Order, and Fluctuations in Apolar Active Smectics
We construct a hydrodynamic theory of noisy, apolar active smectics in bulk suspension or on a substrate. Unlike purely orientationally ordered active fluids, active apolar smectics can be dynamically stable in Stokesian bulk suspensions. Smectic order in these systems is quasilong ranged in dimension $d=2$ and long ranged in $d=3$. …
