Scattering of co-current surface waves on an analogue black hole
Léo-Paul Euvé, Scott Robertson, Nicolas James +2
We report on what is to our knowledge the first scattering experiment of surface waves on an accelerating transcritical flow, which in the Analogue Gravity context is described by…
Nonlinearities induced by parametric resonance in effectively 1D atomic Bose condensates
Scott Robertson, Florent Michel, Renaud Parentani
We present a numerical study of the dynamical effects following a sudden change of the transverse trapping frequency in an elongated Bose-Einstein condensate, which induces periodi…
Gravity waves on modulated flows downstream from an obstacle: The transcritical case
Florent Michel, Renaud Parentani, Scott Robertson
Periodic spatial variations of some parameter arise in analogue gravity experiments aimed at detecting the analogue version of the Hawking effect in a white hole flow. Having the s…
