Simulations of Liquid Bilayer and the Hunt for Protrusions

Abstract

New simulations are reported of a single bilayer immersed in a liquid solvent, using a simple extension of the model of the Max-Plack group and of model used in earlier work. Fluctuation spectrum vel structure factor is dissected in detail and the role of bulk fluctuations is revealed.We propose to search for protrusions direcdtly where they are, i.e. at the solvent-heads boundary. In this context new single-point quantities and new two-point correlations are introduced and determined for the solvent-head pairs. Most unusual shapes are obtained.
