 abstract = {In equilibrium liquid crystals, chirality leads to a variety of
spectacular three-dimensional structures, but chiral and achiral phases
with the same broken continuous symmetries have identical long-time,
large-scale dynamics. In this Letter, starting from active model H*,
the general hydrodynamics of a pseudoscalar in a momentum-conserving
fluid, we demonstrate that chirality qualitatively modifies the dynamics
of layered liquid crystals in active systems in both two and three
dimensions due to an active ``odder″ elasticity. In three dimensions,
we demonstrate that the hydrodynamics of active cholesterics differs
fundamentally from smectic-A liquid crystals, unlike their equilibrium
counterpart. This distinction can be used to engineer a columnar array
of vortices, with an antiferromagnetic vorticity alignment, that can be
switched on and off by external strain. A two-dimensional chiral layered
state-an array of lines on an incompressible, freestanding film of
chiral active fluid with a preferred normal direction-is generically
unstable. However, this instability can be tuned in easily realizable
experimental settings when the film is either on a substrate or in an
ambient fluid.},
