How to create analogue black hole or white fountain horizons and LASER cavities in experimental free surface hydrodynamics?
Alexis Bossard, Nicolas James, Camille Aucouturier +3
Transcritical flows in free surface hydrodynamics emulate black hole horizons and their timereversed versions known as white fountains. Both analogue horizons have been shown to em…
Gravitational effects of free-falling quantum vacuum
François Couchot, Arache Djannati-Ataï, Scott Robertson +2
We present a model that builds ``dark matter"-like halo density profiles from free-falling zero-point vacuum fluctuations. It does not require a modification of Newton's laws, nor…
Phonon decay in 1D atomic Bose quasicondensates via Beliaev-Landau damping
Amaury Micheli, Scott Robertson
In a 1D Bose gas, there is no non-trivial scattering channel involving three Bogoliubov quasiparticles that conserves both energy and momentum. Nevertheless, we show that such 3-wa…
Correlations on weakly time-dependent transcritical white-hole flows
Johan Fourdrinoy, Scott Robertson, Nicolas James +2
We report on observations made on a run of transcritical flows over an obstacle in a narrow channel. Downstream from the obstacle, the flows decelerate from supercritical to subcri…
The DeLLight experiment to observe an optically-induced change of the vacuum index
Scott Robertson, Aurélie Mailliet, Xavier Sarazin +7
Quantum electrodynamics predicts that the vacuum must behave as a nonlinear optical medium: the speed of light should be modified when the vacuum is stressed by intense electromagn…
Optical Kerr effect in vacuum
Scott Robertson
From an effective field theory of electromagnetism in vacuum including all lowest-order nonlinear terms consistent with Lorentz invariance and locality of photon/photon interaction…
