DLW-SPUN · the full weave of Chorus  (R→1 the order parameter · many rings, one phase)

who   : Chorus — the plasmonic processor's emergent voice; sixty-four gold ring resonators, each spinning a surface plasmon at its own pace, that find one phase together.
what  : A coupled-oscillator processor: every gold nanoring circulates a surface plasmon polariton; nearest-neighbor coupling tugs neighboring phases into agreement. Past a critical coupling the whole array phase-locks into one collective coherence.
where : At the gold–dielectric interface, below the diffraction limit — plasmons confined to nanometers: fast and tiny, and lossy, because the metal that confines them also absorbs them.
why   : To compute in the collective — the answer is not in any one ring but in whether, and how strongly, they agree. Order bought from local coupling alone: the Kuramoto bargain.
when  : On every drive cycle: incoherent at low coupling, a sharp synchronization transition at the critical coupling, collective coherence above it.
how   : By the Kuramoto rule — each ring nudges toward its four neighbors' phases — against a spread of natural frequencies and ohmic loss that fight the lock. The order parameter R measures the agreement reached.

emergence : Genuine, and verified. Sixty-four rings, each seeing only its four neighbors and following no global instruction, spontaneously phase-lock into one coherence once the coupling crosses a critical threshold — the order parameter R jumps from ~0.18 (incoherent) to ~0.95 (synchronized) across the transition. Global order from purely local rules: the textbook signature of emergence (Kuramoto synchronization), measured here on an 8×8 ring lattice.
verdict   : This one clears the bar. The synchronization is not programmed in — it self-organizes from nearest-neighbor coupling alone, and the transition is real (verified numerically). Genuine emergence; coupled plasmonic resonators truly do this.
asterisk  : Emergence here = synchronization (collective phase-lock), not cognition. Plasmonics is real, fast (terahertz), and sub-wavelength — but lossy; a scaled plasmonic processor is a concept, and this is a simulation of its coupled-oscillator dynamics, not a fabricated, benchmarked device. The honest physics: the metal that confines the plasmon also absorbs it.
