Bipolaronic superconductivity in the chi field: self-consistent well, plasmonic omegachi, mass threshold and an intrinsically non-adiabatic mechanism (TQNT)

In the Topological Knot Quantum Theory (TQNT) the electron is the trefoil knot 3₁ of the SU (2) Chern-Simons gauge field chi. This letter derives superconductivity as the coherent regime of the self-consistent chi-well dance. The Cooper pair is a link. Two 3₁ knots (braid index 2) bound form a link 2x3₁: even braid parity gives a boson of charge 2e, flux h/2e. No direct force binds two electrons (gravity 10⁴0, magnetic 10⁴ too weak; Coulomb repulsive) ; the binding is the dynamical self-trapping in a shared chi well (bipolaron), with binding energy of a few hundred meV. omegachi is the plasmon. Linearizing the self-consistent feedback (continuity, Euler, Poisson; the self-field being electromagnetism, the low-energy limit of chi) yields omegachi² = n e² / (eps0 m*), i. e. hbar omegachi ~ 4. 6 eV. Being fast (>> phonon), it keeps the bipolaron light (anti-adiabatic), enabling high Tc. Mass threshold. The Frohlich coupling alphaF ~ sqrt (m*) crosses the binding threshold at mc ~ 1-10 mₑ: superconductivity requires heavy carriers (heavy fermions, polaronic superconductors). Eliashberg and lambdaₚl. A linearized Eliashberg solver gives Tc (lambdaₚl) ; the realistic range (1-100 K) corresponds to lambdaₚl ~ 0. 2-0. 3. The electron-plasmon coupling is derived from the plasmon pole of the screened Coulomb interaction, lambdaₚl = (y/4) ln (1+4/y), y= (kTF/kF) ² ~ 0. 66 rₛ, giving ~0. 5 for metals. The bare net lambdaₚl - mu* cancels (omegaₚ ~ EF suppresses retardation). Intrinsically non-adiabatic. The plasmon coupling is forward (Qc ~ 0. 23) and dynamical; the Grimaldi-Pietronero-Strassler vertex correction is positive there and breaks the cancellation, giving a net ~0. 2 and a realistic Tc. Without the vertex the net vanishes: the beyond-Migdal term is the engine, not a correction. Topological phase lock. The pair's internal coherence is fixed by the Chern-Simons phase of the linking (quantized, immune to thermal noise), not by the gravitational metric (whose Colella-Overhauser-Werner-type phase is 10¹2 to 10³5 times too slow between two electrons). Honest status. The quantitative Tc rests on a sensitive cancellation lambdaₚl ~ mu* and requires the full numerical non-adiabatic Eliashberg treatment (vertex P and crossed C, dispersive plasmon, BCS-BEC crossover) ; since omegaₚ ~ EF the expansion is marginal (robust sign, uncertain value).
