Breaking a superfluid harmonic dam: Observation and theory of Riemann invariants and accelerating sonic horizons
Shashwat Sharan, Judith Gonzalez Sorribes, Patrick Sprenger +4
An experimental and theoretical study of sonic horizons emerging from the dam-break problem in a Bose-Einstein condensate confined in an anisotropic harmonic trap is presented. Mea…

An exactly solvable model of wave-mean field interaction in integrable turbulence
T. Congy, G. A. El, M. A. Hoefer
The kinetic theory of soliton gases (SG) is used to develop a solvable model for wave-mean field interaction in integrable turbulence. The waves are stochastic soliton ensembles th…

Solitary wave-mean flow interaction in strongly nonlineardispersive shallow water waves
Thibault Congy, Gennady El, Sergey Gavrilyuk +2
The interaction of a solitary wave and a slowly varying mean background or flow for the Serre-Green-Naghdi (SGN) equations is studied using Whitham modulation theory. The exact for…
