The most popular model of lipid bilayers is the Helfrich model (Helfrich 1973), where the energy per unit area of the membrane depends only on the mean and Gaussian curvatures of the membrane.This …
Web10 feb. 2015 · The Helfrich model only prescribes the dynamics of the surface fluctuations, i.e., the coupled system of OU processes. However, from the above discussion, we see that nondimensionalizing the Eq. for lateral diffusion on this surface gives rise to a natural scaling, corresponding to \((\alpha , \beta )=(0,1)\) in . ...
