摘要：

Lipid membranes which interact via direct hydration forces and which exhibit thermally excited protrusions are studied in the framework of interface models. These models are studied by functional renormalization group methods which predict two different interaction regimes: (i) a protrusion-dominated regime for sufficiently high temperature, and (ii) a hydration-dominated regime for sufficiently low temperature. These predictions are fully confirmed by Monte Carlo simulations. It is also shown that the protrusion-induced roughness of the lipid water interfaces acts to reduce the bending rigidity.
