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…
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…
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…
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…
Scattering of gravity waves in subcritical flows over an obstacle
Scott Robertson, Florent Michel, Renaud Parentani
We numerically study the scattering coefficients of linear water waves on stationary flows above a localized obstacle. We compare the scattering on trans- and subcritical flows, an…
The theory of Hawking radiation in laboratory analogues
Scott Robertson
Hawking radiation, despite being known to theoretical physics for nearly forty years, remains elusive and undetected. It also suffers, in its original context of gravitational blac…
