Structure and Dynamics of Defects in Two-Dimensional Nematic Liquid Crystals
Cody D. Schimming, Daniel A. Beller
Topological defects in nematic liquid crystals have recently received renewed interest due to their important role in non-equilibrium active materials and developing biological sys…
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…
Approach and rotation of reconnecting topological defect lines in liquid crystal
Yohei Zushi, Cody D. Schimming, Kazumasa A. Takeuchi
Topological defects are a universal concept across many disciplines, such as crystallography, liquid-crystalline physics, low-temperature physics, cosmology, and even biology. In n…
Active Nematic Ratchet in Asymmetric Obstacle Arrays
Cody D. Schimming, C. J. O. Reichhardt, C. Reichhardt
We numerically investigate the effect of a periodic array of asymmetric obstacles in a two-dimensional active nematic. We find that activity in conjunction with the asymmetry leads…
Vortex Lattices in Active Nematics with Periodic Obstacle Arrays
Cody D. Schimming, C. J. O. Reichhardt, C. Reichhardt
We numerically model a two-dimensional active nematic confined by a periodic array of fixed obstacles. Even in the passive nematic, the appearance of topological defects is unavoid…
A tensor density measure of topological charge in three dimensional nematic phases
Cody D. Schimming, Jorge Viñals
A path independent measure in order parameter space is introduced such that, when integrated along any closed contour in a three dimensional nematic phase, it yields the topologica…
Friction mediated phase transition in confined active nematics
Cody D. Schimming, C. J. O. Reichhardt, C. Reichhardt
Using a minimal continuum model, we investigate the interplay between circular confinement and substrate friction in active nematics. Upon increasing the friction from low to high,…
Kinematics and dynamics of disclination lines in three-dimensional nematics
Cody D. Schimming, Jorge Viñals
An exact kinematic law for the motion of disclination lines in nematic liquid crystals as a function of the tensor order parameter is derived. Unlike other order param…
Equilibrium morphology of tactoids in elastically anisotropic nematics
Cody D. Schimming, Jorge Viñals
We study two dimensional tactoids in nematic liquid crystals by using a -tensor representation. A bulk free energy of the Maier-Saupe form with eigenvalue constraints o…
Singularity identification for the characterization of topology, geometry, and motion of nematic disclination lines
Cody D. Schimming, Jorge Viñals
We introduce a characterization of disclination lines in three dimensional nematic liquid crystals as a tensor quantity related to the so called rotation vector around the line. Th…
Numerical method for the equilibrium configurations of a Maier-Saupe bulk potential in a Q-tensor model of an anisotropic nematic liquid crystal
Cody D. Schimming, Jorge Viñals, Shawn W. Walker
We present a numerical method, based on a tensor order parameter description of a nematic phase, that allows fully anisotropic elasticity. Our method thus extends the Landau-de Gen…
Anisotropic disclination cores in nematic liquid crystals modelled by a self consistent molecular field theory
Cody D. Schimming, Jorge Viñals
Disclination configurations of a nematic liquid crystal are studied within a self-consistent molecular field theory. The theory is based on a tensor order parameter, and can accomm…
Computational molecular field theory for nematic liquid crystals
Cody D. Schimming, Jorge Viñals
Nematic liquid crystals exhibit configurations in which the underlying ordering changes markedly on macroscopic length scales. Such structures include topological defects in the ne…
Border-Crossing Model for the Diffusive Coarsening of Two-Dimensional and Quasi-Two-Dimensional Wet Foams
C. D. Schimming, D. J. Durian
For dry foams, the transport of gas from small high-pressure bubbles to large low-pressure bubbles is dominated by diffusion across the thin soap films separating neighboring bubbl…
