Paper CLXVI of the One-Octonion Brane-Bulk Series Cooper Pair Inter-Pair Repulsion as AdS₅ Bulk Channel Exclusion: Daix et al. Daix, Dixmerias, He, Verstraten, de Jongh, Peaudecerf, Zhang and Yefsah (2026, Physical Review Letters,

Daix, Dixmerias, He, Verstraten, de Jongh, Peaudecerf, Zhang and Yefsah (2026, Physical Review Letters, DOI: 10. 1103/2t2k-3ftx) report the first direct imaging of Cooper pair inter-pair correlations in a 2D Fermi gas of ⁶Li atoms. Using atom-by-atom snapshot imaging and exact quantum Monte Carlo simulation, they find that the pair-pair correlation function g ² (r) drops below unity at short pair separations — Cooper pairs ⁻ ⁾ actively repel neighboring pairs, maintaining a minimum spacing. BCS theory, which treats the condensate as a mean field with no inter-pair correlations, predicts g ² = 1 at all separations and cannot account for this ⁻ ⁾ dip. The One-Octonion Brane-Bulk Framework (Papers XLIV and CLXIV, Jagadeesan 2025–2026) provides a natural explanation. Paper XLIV established that Cooper pairs are phase-locked T2 coherent zones and Type II vortices are topological brane threads whose repulsion forms the Abrikosov lattice. Paper CLXIV (April 2026) established that the Cooper pair is a coherent brane-to-bulk-to-brane transit through the interference-free AdS₅ bulk: two electrons that find a common brane thread travel through the bulk together, phase-coherent, and return to the brane as a standing wave. The inter-pair repulsion observed by Daix et al. is the direct consequence: two brane threads cannot share the same AdS₅ bulk region. The bulk channel has a topological hard core of radius ξ (the T2* coherence length = Cooper pair coherence length). When two pairs approach within r < ξ, their bulk channels attempt to overlap, generating destructive interference in the bulk — the pairs are expelled. The dip in g ² (r) is the brane-surface signature of this bulk ⁻ ⁾ exclusion. We derive a quantitative prediction: ∫ 1 − g ² ₚair (r) d²r = πξ² (the excluded brane area per ⁻ ⁾ pair), testable against the Daix et al. data. We further identify Daix et al. 's 'dancing couples keeping distance' metaphor as a precise physical description: each pair occupies its own bulk channel on the AdS₅ dance floor; channels are exclusive.
