DUPRAT, C. ... (et al.), 2009. Liquid film coating a fiber as a model system for the formation of bound states in active dispersive-dissipative nonlinear media. Physical Review Letters, 103 (23), 234501.
We analyze the coherent-structure interaction and the formation of bound states in active dispersivedissipative
nonlinear media using a viscous film coating a vertical fiber as a prototype. The coherent
structures in this case are droplike pulses that dominate the evolution of the film.We study experimentally
the interaction dynamics and show evidence for formation of bound states. A theoretical explanation is
provided through a coherent-structures theory of a simple model for the flow.
