The paper's transferable asset is a critical interface mechanism in which a localized zero mode survives without a mass or spectral gap: topology is encoded by a sign reversal of a first-derivative coefficient rather than by a conventional mass sign change. This suggests a sequence-state module whose differential operator contains a sign-changing transport coefficient and therefore produces boundary- or interface-localized features. The benefit is speculative rather than established, but it provides a concrete inductive bias for detecting change points, localized anomalies, or transitions without relying on sharply separated eigenvalues. The most direct test is a small sequence model comparing critical-interface pooling against ordinary convolution, mean pooling, and attention on tasks with localized relevant regions.
Add a fixed or weakly learned interface-localized branch to a sequence model. Set the critical mass term to zero and make the transport coefficient change sign across a learnable interface, producing a localized mode that pools information near a detected transition rather than averaging uniformly over the sequence.
