    "abstract": "When a capillary is inserted into a liquid, the liquid will rapidly flow into\nit. This phenomenon, well studied and understood on the macroscale, is\ninvestigated by Molecular Dynamics simulations for coarse-grained models of\nnanotubes. Both a simple Lennard-Jones fluid and a model for a polymer melt are\nconsidered. In both cases after a transient period (of a few nanoseconds) the\nmeniscus rises according to a $\\sqrt{\\textrm{time}}$-law. For the polymer melt,\nhowever, we find that the capillary flow exhibits a slip length $\\delta$,\ncomparable in size with the nanotube radius $R$. We show that a consistent\ndescription of the imbibition process in nanotubes is only possible upon\nmodification of the Lucas-Washburn law which takes explicitly into account the\nslip length $\\delta$.",
