Hybridization of Machida-Shibata states under small on-site repulsion produces DIII topological superconductivity with Kramers Majorana pairs in chains and helical edge modes in 2D lattices.
NCL crystals exhibit boson-peak-like glassy anomalies from low-energy optical phonons and anomalous linear-T resistivity explained by electron scattering off overdamped phonons.
