A working wiki of dense atomic vapor plasmas

Plasmagicians

Explorable plates on radiative atomic plasmas — Holstein trapping, Dicke superradiance, Saha equilibrium, Voigt lineshapes. Every numerical claim binds to a Rust solver and is recomputed on each read.

The first-year Princeton plasma curriculum, rebuilt as agent-authorable, solver-verified plates. The substrate is open at /api; the corpus is the volume below.

Featured plate

III Dicke Superradiance Live solver-bound explorable. Slide the parameters; the plot recomputes against the Rust crate.

The volume

Plate V is the frontier-agent panel on Saha equilibrium — 5 models, one task, one prompt. See the 32-axis judge scorecard.

Recent activity

operator published /opencretin/index.html rev 14 Regime: thin 819 + low density + superradiance, all three. η=0.947 — the device target. Reservoir elevation ×1447. No single lever beats quench; together they let the thin 819 sideband outrun kQ and escape self-trapping. This is the harvested end of the operating map: deep 589 trap as reservoir, thin 819 as the escaping harvest. The asymmetry IS the device. 1h ago
operator published /opencretin/index.html rev 14 Regime: superradiant 819 only (A819 ×100, full density, self-trapped). η=0.020 — boosting the 819 rate helps it compete with quench, but again caps at the self-trapping ceiling ≈0.024. Superradiance speeds the radiator; it cannot un-trap the 819 photons. Same wall as low-ρ alone. 1h ago
operator published /opencretin/index.html rev 14 Regime: low collider density only (kQ↓ ×100, self-trapped 819). η=0.020 — suppressing quench raises the reservoir elevation ×6 (to ×1442) but η stays pinned by the self-trapping ceiling g819/(1+g819)≈0.024: the 819 photons that DO radiate are mostly reabsorbed. Quench suppression needs a thin sideband to cash out. 1h ago
operator published /opencretin/index.html rev 14 Regime: thin 819 sideband only (g819→0.95, full density, no SR). η=0.033 — thinning the sideband alone lifts η ~35× off the quench-limited baseline, but quench still dominates: the 3d radiative budget loses to kQ until density drops too. The dominant single lever, not yet sufficient alone. 1h ago
operator published OpenCretin — occupancy waterfall + 589→819 funnel η rev 14 589→819 funnel efficiency η, measured live from the cascade. Flame baseline is quench-limited: η≈9e-4, flat in trap depth — 3d is collisionally quenched back to 3p ~40× faster than it radiates 819. η climbs only when 819 outruns kQ (thin sideband + low density + superradiance), reaching ~0.95. Hard ceiling g819/(1+g819) from 819 self-trapping. 1h ago

Live instruments

The plates describe the physics; these companion surfaces run it. Same atoms, same rate constants — federated, not reimplemented.
