Query: Dry active turbulence in microtubule-motor mixtures   We study the dynamics and phase behaviour of a dry suspension of microtubules
and molecular motors. We obtain a set of continuum equations by rigorously
coarse graining a microscopic model where motor-induced interactions lead to
parallel or antiparallel ordering. Through numerical simulations, we show that
this model generically creates either stable stripes, or a never-settling
pattern where stripes periodically form, rotate and then split up. We derive a
minimal model which displays the same instability as the full model, and
clarifies the underlying physical mechanism. The necessary ingredients are an
extensile flux arising from microtubule sliding and an interfacial torque
favouring ordering along density gradients. We argue that our minimal model
unifies various previous observations of chaotic behaviour in dry active matter
into a general universality class.
