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…

The Role of Elastic Anisotropy in Active Nematics
Alexander J. H. Houston
We analyse the effect of anisotropy in elastic constants on the hydrodynamics of active nematics. Building on the multipole framework for a single elastic constant, we determine th…

Spontaneous Flows and Quantum Analogies in Heterogeneous Active Nematic Films
Alexander J. H. Houston, Nigel J. Mottram
Incorporating the inherent heterogeneity of living systems into models of active nematics is essential to provide a more realistic description of biological processes such as bacte…
