Yichen’s paper on Kramers nodal lines in intercalated TaS2 superconductors was published on Nat. Commun.! Congratulations to everyone involved!

In this work, we establish an ideal Kramers nodal line (KNL) system. By intercalating the transition metal dichalcogenide 2H-TaS2 with a fractional amount of indium, a KNL arises at the Fermi level due to the combined effects of broken inversion symmetry, mirror symmetry protection, and nonstoichiometry. Using spin-resolved angle-resolved photoemission spectroscopy (ARPES), ab-initio-based one-step model ARPES calculations, and angle-dependent quantum oscillation experiments, the KNLs are demonstrated not only in the ideal case of In0.5TaS2 but also across the isostructural family. Such a discovery pertains to potential applications in spintronics, valleytronics, optoelectronics and facilitates the exploration in topological superconductivity.
