First-Principles Theory of Steady-State Thermonuclear Confinement: Solenoidal Vorton Dynamics, Anisotropic Inverse Energy Cascades, and Ponderomotive Mode Locking

The first-principles thermonuclear confinement framework establishes continuous plasma stability by coupling topological relaxation, spectral self-organization, and nonlinear optical mode locking into a self-sustaining burn balance: Relaxation to Force-Free Equilibrium: Visco-resistive reconnection within regularized solenoidal vortex filaments dissipates magnetic energy while strictly conserving global magnetic helicity. This separation of timescales drives the magnetized plasma into a minimum-energy, force-free Beltrami state where the Lorentz force vanishes, eliminating the primary drive for macroscopic interchange disruptions. Anisotropic Inverse Energy Cascade: Imposing a strong toroidal guide magnetic field reduces cross-field drift dynamics to a two-dimensional regime governed by dual conservation of kinetic energy and generalized potential enstrophy. These dual invariants forbid forward energy cascades, redirecting turbulent kinetic energy upward into macroscopic, radially sheared poloidal zonal flows. Turbulence Quenching via Velocity Shear: The intense radial shearing rate generated by the zonal flows exceeds the maximum linear growth rates of microscale drift-wave instabilities. This shearing tears apart turbulent eddies and quenches anomalous cross-field thermal diffusivity down to the neoclassical baseline. Active Tearing Island Suppression: Dual-frequency laser beat waves produce a localized ponderomotive envelope matched to the local plasma frequency at resonant magnetic surfaces. The resulting non-inductive parallel current forces the tearing mode stability index negative, arresting magnetic island growth and preserving magnetic flux surface integrity. Steady-State Lawson Burn: Reducing turbulent thermal transport to neoclassical levels elevates the global energy confinement time by an order of magnitude above empirical turbulent scaling laws. This satisfies the Lawson ignition criterion at standard core temperatures and modest magnetic fields, sustaining continuous energy production without thermal collapse.
