We establish nonperturbatively that the nodal structure of the interactions gives rise to long-lived quasiparticle excitations that result in a diverging diffusion constant, even though the system is fully chaotic. Using a Boltzmann equation approach, we find that the charge mode acquires an anomalous dispersion relation at long wavelength ωðqÞ ∼ qz with dynamical exponent z ¼ min½ð2n þ dÞ=2n; 2, where n is the order of the nodal point in momentum space. We verify our predictions in one-dimensional systems using tensor-network techniques.","lang":"eng"}],"department":[{"_id":"MaSe"}],"article_processing_charge":"Yes (via OA deal)","oa_version":"Published Version","external_id":{"arxiv":["2501.08381"]},"publication":"Physical Review Letters"}
