Abstract

Simulations of a bilayer in a liquid solvent in the full range of areas from the floppy to the extended state also show the hole/tunnel spontaneous formation. Whether this change of topology is preceded by topological fluctuations of the Gaussian curvature K(x,y) is an open question. Probability distributions of Gaussian curvature are transformed into those of the ordered inverse radii; these new shapes show a gradual change along the isotherm. The model of Max-Planck group with 5 beads is used, amended to represent amphiphiles in the spirit of the "coarse-grained" or "Martini" force field.
