Defect Dynamics in Cholesterics: Beyond the Peach-Koehler Force
Joseph Pollard, Richard G. Morris
The Peach-Koehler force between disclination lines was originally formulated in the study of crystalline solids, and has since been adopted to provide a notion of interactions betw…
Morse Theory and Meron Mediated Interactions Between Disclination Lines in Nematics
Joseph Pollard, Richard G. Morris
The topological understanding of nematic liquid crystals is traditionally centered on singularities, or defects, and their classification via homotopy theory. However, this approac…
Gauge Freedom and Objective Rates in the Morphodynamics of Fluid Deformable Surfaces: the Jaumann Rate vs. the Material Derivative
Joseph Pollard, Sami Al-Izzi, Richard G. Morris
Morphodynamic descriptions of fluid deformable surfaces are relevant for a range of biological and soft matter phenomena, spanning materials that can be passive or active, as well…
Escape into the Third Dimension in Cholesteric Liquid Crystals
Joseph Pollard, Gareth P. Alexander
Integer winding disclinations are unstable in a nematic and are removed by an `escape into the third dimension', resulting in a non-singular texture. This process is frustrated in…
