Weyl semimetals (WSMs) provide a platform to realize long-sought massless Weyl fermions, which can host a variety of exotic quantum phenomena such as chiral anomalies and anomalous Hall conductivity. The most intriguing nature of WSMs is the emergence of an unconventional surface state called a Fermi arc, which is distinct from the well-known Fermi surface of ordinary metals. The authors have used angle-resolved photoemission spectroscopy on NbP and succeeded in observing the electronic states for two differently terminated surfaces of this noncentrosymmetric crystal. Corroborated by first-principles calculations, it is unambiguously demonstrated that NbP is a Weyl semimetal with reduced spin-orbit coupling, exhibiting a drastic difference in the Fermi-surface topology between the P- and Nb-terminated surfaces. Through a direct comparison of Fermi-arc surface states between the two surfaces, the momentum location of Weyl nodes has been elucidated. The present results provides a pathway for exploring new quantum phenomena utilizing Fermi-arc properties of WSMs.

Unconventional superconductors, with order parameters that are predicted to have short range spatial modulations, have held long standing interest in the field. The Josephson effect, which directly probes the strength of the pairing potential is an ideal technique to study these materials, in contrast to a majority of probes which rely on deductions made from quasiparticle measurements. The authors combine the Josephson effect with the high spatial resolution afforded by scanning tunneling microscopy to study atomic scale variations of the order parameter in a model system consisting of magnetic adatoms on a BCS superconductor. The atomic resolution achieved establishes scanning Josephson spectroscopy as a promising tool for the study of novel superconducting materials.
