Absolute vs Convective Instabilities and Front Propagation in Lipid Membrane Tubes
Joël Tchoufag, Amaresh Sahu, Kranthi K. Mandadapu
We analyze the stability of biological membrane tubes, with and without a base flow of lipids. Membrane dynamics are completely specified by two dimensionless numbers: the well-kno…
Active Contact Forces Drive Non-Equilibrium Fluctuations in Membrane Vesicles
Sho C. Takatori, Amaresh Sahu
We analyze the non-equilibrium shape fluctuations of giant unilamellar vesicles encapsulating motile bacteria. Owing to bacteria--membrane collisions, we experimentally observe a s…
Geometry and dynamics of lipid membranes: The Scriven--Love number
Amaresh Sahu, Alec Glisman, Joël Tchoufag +1
The equations governing lipid membrane dynamics in planar, spherical, and cylindrical geometries are presented here. Unperturbed and first-order perturbed equations are determined…
Arbitrary Lagrangian--Eulerian finite element method for curved and deforming surfaces. I. General theory and application to fluid interfaces
Amaresh Sahu, Yannick A. D. Omar, Roger A. Sauer +1
An arbitrary Lagrangian--Eulerian (ALE) finite element method for arbitrarily curved and deforming two-dimensional materials and interfaces is presented here. An ALE theory is deve…
The irreversible thermodynamics of curved lipid membranes
Amaresh Sahu, Roger A. Sauer, Kranthi K. Mandadapu
The theory of irreversible thermodynamics for arbitrarily curved lipid membranes is presented here. The coupling between elastic bending and irreversible processes such as intra-me…
