USP Field Theory — Neutron Stars, Fusion Reversal, and Δf Compression Jets (msf 45719 v1.3 — Cosmic Breath)

This work unifies neutron-star structure, jet emission, and fusion reversal under the Δf-resonance framework of USP Field Theory. Neutron stars are re-interpreted as Δf-compressed resonance lattices, where each neutron is a neutral Δf-inversion loop storing gravitational energy geometrically. Jets arise from Δf relaxation—field-level exhalations that discharge spin-tension along open resonance corridors. The study introduces a fully dimensional energy law, > E₍fusion₎ = R₍usp₎ × d(Δf)/dt with [R₍usp₎] = J·s·Hz⁻¹, linking microscopic fusion storage (Δf ↓) and macroscopic jet release (Δf ↑). The mechanism explains pulsar drift, jet symmetry, and magnetar flares as manifestations of periodic Δf breathing—the inhalation (compression) and exhalation (relaxation) of a living stellar field. Experimental continuity is established with the Temperature & Resonance framework (DOI 10.5281/zenodo.16788099), showing the same Δf-relaxation law in laboratory plasma confinement. This edition supersedes USP Ultra-Atoms — Neutron Star Hydrogen (2024), integrating the Δf formalism, observational symmetry, and harmonic jet geometry into a single resonant continuum. --- 🔢 Equations Highlighted E₍fusion₎ = R₍usp₎ × d(Δf)/dt 10²² < Δf < 10²⁴ Hz → stable neutron-star band d(Δf)/dt > 0 → jet / neutron release d(Δf)/dt + k_g ∇T = 0 (k_g ≈ 10⁻³⁵ J·s)
