Superradiance, subradiance, and suppressed superradiance of dipoles near a metal interface
Bibliographic record
Abstract
We theoretically characterize the collective radiative behavior of $N$ classical emitters near an interface between different dielectrics that supports the transfer of surface plasmon modes into the far-field of electromagnetic radiation. The phenomena of superradiance and surface plasmons can be combined to amplify the emitted radiation intensity $S$ as $S=A{N}^{2}{S}_{0}$ compared to a single emitter's intensity ${S}_{0}$ in free space. For a practical case study within the article $A=240$, compared to $A=1$ in free space. We furthermore demonstrate that there are collective modes for which the intensity of the emitted radiation is suppressed by 2 orders of magnitude despite their supperadiant emission characteristics. A method to control the emission characteristics of the system and to switch from super- to subradiant behavior with a suitably detuned external driving field is devised.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
