Research context

  • Generalized sector coupling

    A common interaction on arbitrary nested sectors yields reciprocal responses, normalized vertices, and testable coupling relations, with neutrinos as a channel-specific control.

  • Rotations of nested spatial sectors

    A rotation preserving every fixed member of the nested spatial chain has a restricted block structure, while rotating the whole chain requires the moving embeddings in the projected dynamics.

  • Spatial transport of a neutral doublet

    The two neutral polarizations of a balanced five-dimensional rotation carry a nonzero traceless geometric curvature when its physical null axis varies, with an exact spatial kinetic-energy decomposition.

  • Polarized photon transition strength

    Summing all spinor response directions gives an exact two-polarization transition matrix for a simple spatial Pauli probe, including helicity-sensitive zeros and a nonzero total-strength bound at every tested depth.

  • Reciprocal scattering of spatial modes

    A solved conservative wave model turns a two-sided spatial overlap into reflection and transmission, separating protected polarization mismatch from narrow resonances and coherent transparency.

  • Rotation-neutral spatial modes

    A common rotation of two spatial planes has an exact neutral spinor subspace, while three equal planes have none; full spatial motion and dynamical selection determine whether this can become a particle coupling rule.

  • Transition-density coupling

    The complete derivative of a bilocal density interaction pairs both objects' transition densities, giving reciprocal mode vertices and an exact signed quadrupole matching law from the existing spatial kernel.
