Record completeness
Claims
The interplay between electronic correlation, spin-orbit coupling and the noncentrosymmetric I4mm crystal symmetry stabilize flat topological nodal lines within 10 meV of the Fermi level, which could contribute a significant density of states.
That the DFT+DMFT calculations faithfully reproduce the topological character and flatness of the nodal lines without significant artifacts from the chosen interaction parameters or the single-site DMFT approximation.
CeCoGe3 is a topological nodal line Kondo semimetal in which correlations and spin-orbit coupling stabilize flat nodal lines near the Fermi level that may mediate pressure-induced superconductivity.
