Fluctuation spectrum of fluid membranes coupled to an elastic meshwork: jump of the effective surface tension at the mesh size

Jean-Baptiste Fournier, David Lacoste, Elie Raphael

We identify a class of composite membranes: fluid bilayers coupled to an elastic meshwork, that are such that the meshwork's energy is a function $F_{\mathrm{el}}[A_{\xi }]$ \textit{not}…
