Three-Dimensional Spontaneous Flow Transition in a Homeotropic Active Nematic
Vincenzo J. Pratley, Enej Caf, Miha Ravnik +1
We study the three-dimensional spontaneous flow transition of an active nematic in an infinite slab geometry using a combination of numerics and analytics. We show that it is deter…
