The Korteweg-de Vries (KdV) equation is derived from Landau two-fluid hydrodynamics applied to the thickness oscillation of the superfluid 4He film at low temperatures, where the main restoring force is van der Waals attraction from the substrate and the thermomechanical force due to phonons is a sm

While there has been considerable theoretical attention given to nonlinear (soliton) effects for adsorbed films of superfluid 4He, there have been no systematic experimental studies. In this paper we report measurements of wave propagation in such films with drive levels varying over five orders of
