Curvature driven flow of bi-layer interfaces

WebFig. 4.1. The modified potential G for α > α∗ (solid) and α = α∗ (dotted). At α = α∗ the potential G has a double zero at u = φ∗m(b). Increasing the value of α above α∗ lowers G about its pivot point at u = b, where it maintains a double zero. The double zero at u = φ∗m breaks into two zeros of G, the smaller of which, denoted φm , is also the maximum of … WebDec 31, 2016 · We investigate the stability and slow geometric evolution of multicomponent bilayer interfaces within the context of an \(H^{-1}\) gradient flow of the mFCH, addressing the impact of aspect ratio of the amphiphile (lipid or copolymer unit) on the intrinsic curvature and the codimensional bifurcation. In particular we derive a Canham–Helfrich ...
