Orienting-Field Effects on Instability and Mode Selection in Active Nematics
I. K. Joseph, A. J. H. Houston, K. N. Kowal +1
We examine the instabilities of a confined active nematic subjected to an orienting field using a low Reynolds number Ericksen-Leslie framework with active stresses and field-induc…

Heterogeneity-Induced Oscillations in Active Nematics
Alexander J. H. Houston, Michael Grinfeld, Geoff McKay +1
One of the defining features of active nematics is that above a critical activity the quiescent state becomes unstable to a distorted, flowing one. We show that spatial variations…

Delayed transitions, promoted states and multistability in a pressure-driven nematic under an electric field
G. McKay, N. J. Mottram
We consider the effects of an applied pressure gradient on the classical Freedericksz transition, finding a delayed transition, the promotion of particular director configurations…
