Guiding isotropic active fluids with anisotropic friction
Cody D. Schimming, Brian A. Camley
Inspired by recent experiments of cells accumulating on anisotropic substrates, we study a two-dimensional, compressible, isotropic, active fluid in the presence of anisotropic fri…
Defect Interactions Through Periodic Boundaries in Two-Dimensional -atics
Cody D. Schimming
Periodic boundary conditions are a common theoretical and computational tool used to emulate effectively infinite domains. However, two-dimensional periodic domains are topological…
Turbulence to order transitions in activity patterned active nematics
Cody D. Schimming, C. J. O. Reichhardt, C. Reichhardt
We numerically study two-dimensional active nematics with periodic activity patterning. For stripes of activity, we observe a transition from two-dimensional to one-dimensional act…
Analytical model for the motion and interaction of two-dimensional active nematic defects
Cody D. Schimming, C. J. O. Reichhardt, C. Reichhardt
We develop an approximate, analytical model for the velocity of defects in active nematics by combining recent results for the velocity of topological defects in nematic liquid cry…
