EVE-χ is a theoretical research program investigating whether a physical defect in matter can become a genuine topological excitation of a coupled light–matter order parameter and thereby activate an autonomous, self-extinguishing repair channel. The central hypothesis is that a material defect can induce a signed or quantized polaritonic response, drive the creation, attraction, or transport of an inverse material topological excitation, and terminate the repair process automatically when the restored configuration returns the hybrid system to a topologically trivial dark or low-dissipation state.

The work develops and adversarially tests several formulations using condensed-matter theory, polariton physics, topological photonics, open quantum systems, nonlinear field theory, and nonequilibrium statistical mechanics. Its strongest results include a relative-homotopy healability criterion,

HEVE=ker⁡\[i∗:π1(N)→π1(M)\],\\mathcal H\_{\\mathrm{EVE}}=\\ker\[i\_\*:\\pi\_1(N)\\rightarrow\\pi\_1(M)\],

which determines when a material defect becomes contractible after enlargement into a hybrid light–matter order-parameter manifold; a Dirac-index formulation in which material-defect winding controls the chirality and number of hybrid defect-bound modes; defect-activated confinement and annihilation dynamics; explicit no-go conditions; thermodynamic consistency requirements; open-system and driven-dissipative models; and quantitative comparisons with conventional nontopological feedback.

The project distinguishes established ingredients from new hypotheses and does not claim that polariton vortices, BICs, topological defect modes, autonomous feedback, or vortex annihilation are individually novel. The narrow proposed new-physics target is a driven light–matter response regime in which material topology is physically transduced into a hybrid topological defect response that generates a corrective material topological current and disappears upon successful annihilation. A stronger future result would be the experimental demonstration of a distinct nonequilibrium self-healing phase or a genuinely new mixed material–light topological response invariant.

The repository/archive contains the full theoretical dossiers, numerical models, source code, reproducibility data, figures, convergence tests, novelty audits, falsification criteria, and proposed minimum experiments.

Scientific status: theoretical proposal and falsifiable research program; not an experimental discovery.
