Nonequilibrium Fluctuations, Traveling Waves, and Instabilities in Active Membranes
Nonequilibrium Fluctuations, Traveling Waves, and Instabilities in Active Membranes
The stability of a flexible fluid membrane containing a distribution of mobile, active proteins (e.g., proton pumps) is shown to depend on the structure and functional asymmetry of the proteins. A stable active membrane is in a nonequilibrium steady state with height fluctuations whose statistical properties are governed by the …
