Calculation record

Check reciprocal spatial resonances on fully dressed local Dirac branches.

The particle indices are unchanged. The specified local scalar law is a
control, not a mass fit, a measured decay mechanism or a selected geometry.

Research context

  • Reciprocal scalar response of excited spatial branches

    A near-resonance derived from the common scalar action predicts spatial instabilities on nonlinearly dressed branches at the unchanged assigned indices, with converged full differential residuals and a direct constraint on the coupling response required by an inverse mass law.
