Resumen:
We consider nanometer-sized fluid annuli (rings) deposited on a solid
substrate and ask whether these rings break up into droplets due to the
instability of Rayleigh-Plateau-type modified by the presence of the
substrate, or collapse to a central drop due to the presence of
azimuthal curvature. The analysis is carried out by a combination of
atomistic molecular dynamics simulations and a continuum model based on a
long-wave limit of Navier?Stokes equations. We find consistent results
between the two approaches, and demonstrate characteristic dimension
regimes which dictate the assembly dynamics.
