Molecular interfacial rheology: Lipid membrane shear viscosity
Zhi-Xun Xu, Amaresh Sahu
We develop a method to extract the shear viscosity of a lipid membrane from equilibrium molecular dynamics simulations. The method characterizes the rheology of general interfacial…
Three-slab model for the dielectric permittivity of a lipid bilayer
M. M. B. Sheraj, Amaresh Sahu
A model for the tensorial dielectric permittivity of phospholipid membranes is presented here. The four-nanometer-thick membrane is treated as a composite made up of three dielectr…
Osmotic forces modify lipid membrane fluctuations
Amaresh Sahu
In hydrodynamic descriptions of lipid bilayers, the membrane is often approximated as being impermeable to the surrounding, solute-containing fluid. However, biological and in vitr…
Arbitrary Lagrangian--Eulerian finite element method for lipid membranes
Amaresh Sahu
An arbitrary Lagrangian--Eulerian finite element method and numerical implementation for curved and deforming lipid membranes is presented here. The membrane surface is endowed wit…
