  • The origin of the photoemission replica bands in monolayer FeSe/SrTiO3 remains controversial. Here, the authors perform angle-resolved photoemission spectroscopy with polarized photon on FeSe/SrTiO3 and observe high-order replica bands with high intensity from various Fe 3d bands, suggesting a mixed mechanism.

  • The underlying mechanism of iron-based superconductivity, the role of electron correlations, and the extent to which the behavior resembles those of the cuprates has been debated since their discovery. Here, using angle resolved photoemission spectroscopy, the authors report reconstruction of the Fermi surface for FeTe1−xSex driven by orbital-dependent correlation effects in the absence of symmetry breaking and find evidence for an orbital-selective Mott transition.

  • Kramers Nodal Lines (KNLs) have been theoretically proposed as special Weyl line degeneracies connecting time-reversal invariant momenta, but their observation in quantum materials is not established. Combining ARPES experiments with DFT calculations, the authors identify SmAlSi and its isostructural family as viable materials to host KNLs.
