Dynamic Theory of Pearling Instability in Cylindrical Vesicles

arXiv:cond-mat/9410104 · doi:10.1103/PhysRevLett.74.3384

Abstract

We give a simple theory for recent experiments of Bar-Ziv and Moses% Phys. Rev. Lett. {\bf73} (1994) 1392, in which tubular vesicles are excited using laser tweezers to a ``peristaltic'' state. Considering the hydrodynamics of a bilayer membrane under tension, we reproduce some of the qualitative behavior seen and find a value for the wavelength of the instability in terms of independently measured material parameters, in rough agreement with the experimental values.
