Abstract
Using superfluid optomechanical system, here we show both that radiation pressure can greatly deform superfluid film, increasing its local thickness by over a factor of 2, and that this generates new sound modes within the film locally, that are confined by the optical mode and interact strongly with it. This demonstrates a new form of dynamical backaction between the intensity of light within a cavity and the shape of the mechanical eigenmodes that it creates.
