Integer defects, flow localization, and bistability on curved active surfaces
Rushikesh Shinde, Raphaël Voituriez, Andrew Callan-Jones
Biological surfaces, such as developing epithelial tissues, exhibit in-plane polar or nematic order and can be strongly curved. Recently, integer (+1) topological defects have been…
Theory of nematic and polar active fluid surfaces
Guillaume Salbreux, Frank Jülicher, Jacques Prost +1
We derive a fully covariant theory of the hydrodynamics of nematic and polar active surfaces, subjected to internal and external forces and torques. We study the symmetries of pola…
Hydrodynamics of bilayer membranes with diffusing transmembrane proteins
Andrew Callan-Jones, Marc Durand, Jean-Baptiste Fournier
We consider the hydrodynamics of lipid bilayers containing transmembrane proteins of arbitrary shape. This biologically-motivated problem is relevant to the cell membrane, whose fl…
Active Gel Model of Amoeboid Cell Motility
A. C. Callan-Jones, R. Voituriez
We develop a model of amoeboid cell motility based on active gel theory. Modeling the motile apparatus of a eukaryotic cell as a confined layer of finite length of poroelastic acti…
Nematic cells with defect-patterned alignment layers
Adam S. Backer, A. C. Callan-Jones, Robert A. Pelcovits
Using Monte Carlo simulations of the Lebwohl--Lasher model we study the director ordering in a nematic cell where the top and bottom surfaces are patterned with a lattice of $\pm 1…
Untwisting of a Strained Cholesteric Elastomer by Disclination Loop Nucleation
A. C. Callan-Jones, Robert A. Pelcovits, Robert B. Meyer +1
The application of a sufficiently strong strain perpendicular to the pitch axis of a monodomain cholesteric elastomer unwinds the cholesteric helix. Previous theoretical analyses o…
