Rousseaux, Germain, Mathis, Christian, Maissa, Philippe, Philbin, Thomas G., Leonhardt, Ulf
The conversion of positive-frequency waves into negative-frequency waves at the event horizon is the mechanism at the heart of the Hawking radiation of black holes. In black-hole analogues, horizons...
Destabilization of a Viscous Film Flowing Down in the Form of a Vertical Cylindrical Curtain (2006)
Pirat, Christophe, Mathis, Christian, Mishra, Manoranjan, Maissa, Philippe
In this Letter, we study experimentally a viscous liquid curtain in an annular geometry. Gap and median radius can be varied in such a way that the base of the initially stationary cylindrical...
Transition to Spatiotemporal Chaos in a Two-Dimensional Hydrodynamic System (2005)
Pirat, Christophe, Naso, Aurore, Meunier, Jean-Louis, Maissa, Philippe, Mathis, Christian
We study the transition to spatiotemporal chaos in a two-dimensional hydrodynamic experiment where liquid columns take place in the gravity induced instability of a liquid film. The film is formed...
