Non-linear Processes and Stimulated Hawking Radiation in Hydrodynamics\n for Decelerating Subcritical Free Surface Flows with a Subluminal Dispersion\n Relation
Bibliographic record
Abstract
In \\cite{PRL2011}, the authors have {\\it "conducted experiments in order to\nverify the thermal nature of the stimulated Hawking process at a white hole\nhorizon in a fluid analogue gravity system"} namely the linear mode conversion\ngiving rise to negative energy waves i.e. the classical ingredient at the root\nof the Hawking effect in astrophysics. However, here we show that these\nexperiments in Vancouver operated in a weakly non-linear regime that obscure\nthem as was the case for the seminal experiments in Nice within a stronger\nnon-linear regime \\cite{NJP2008}. We finally shed some light on these matters\nby demonstrating that the linear conversion of water waves on a counter-current\ntakes place with or without a dispersive white hole horizon as anticipated in\nthe Nice experiment no matter the frequency is conserved within the entire\nprocess provided there is an absence of wave breaking during the wave-current\ninteraction. The main novelty is the role of free (and not forced as usual in\nnon-linear effects) harmonics generation in the interpretation of both the Nice\n(for at least the stimulating mode) and Vancouver (for the converted modes\nonly) experiments. Unfortunately, the thermality of the spectrum is not\ndemonstrated in the Poitiers reproduction of the Vancouver experiments based on\nthe analysis of the scattering coefficients themselves and not just of their\nratio as was done previously.\n

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
