Enhanced transverse diffusion in active biomembranes Academic Article uri icon


  • Abstract We study the transverse diffusion of a tagged membrane point in membranes that include active sites, such as ion pumps. At very short times we find a subdiffusive behavior< r 2>∼ t 2/3 as for passive membranes. At long times we find a few regimes which show a strongly enhanced diffusion,< r 2>∼ t α with 1< α< 2. One of the regimes shows a purely ballistic motion α= 2.
