Deformations of the geometry of lipid vesicles
Riccardo Capovilla, Jemal Guven, Jose' Antonio Santiago
Consider a closed lipid membrane (vesicle), modeled as a two-dimensional surface, described by a geometrical hamiltonian that depends on its extrinsic curvature. The vanishing of i…
Lipid membranes with an edge
R. Capovilla, J. Guven, J. A. Santiago
Consider a lipid membrane with a free exposed edge. The energy describing this membrane is quadratic in the extrinsic curvature of its geometry; that describing the edge is proport…
Geometry of lipid vesicle adhesion
Riccardo Capovilla, Jemal Guven
The adhesion of a lipid membrane vesicle to a fixed substrate is examined from a geometrical point of view. This vesicle is described by the Helfrich hamiltonian quadratic in mean…
Stresses in lipid membranes
Riccardo Capovilla, Jemal Guven
The stresses in a closed lipid membrane described by the Helfrich hamiltonian, quadratic in the extrinsic curvature, are identified using Noether's theorem. Three equations describ…
