Time and length scales in lipid bilayer simulations

Time and length scales for different kinds of local and collective motions in lipid bilayers that may be probed in molecular dynamics simulations are discussed. The possibility to determine parameters in continuum models using simulation techniques is discussed. Agreements and discrepancies between simulations and experimental data are presented and discussed. The chapter covers large scale undulations and peristaltic thickness fluctuations, hydrocarbon chain reorientation motion, lipid lateral diffusion and motion of the entire monolayers with respect to each other and with respect to the water.
