  The interplay between topology and superconductivity in quantum materials
harbors rich physics ripe for discovery. In this study, we investigate the
topological properties and superconductivity of the nonsymmorphic chiral
superconductor NbGe$_2$ using high-resolution angle-resolved pho-toemission
spectroscopy (ARPES), transport measurements, and ab initio calculations. The
ARPES data revealed exotic chiral surface states on the (100) surface
originating from the inherent chiral crystal structure. Supporting calculations
indicate that NbGe$_2$ likely hosts elusive Weyl fermions in its bulk
electronic structure. Furthermore, we uncovered the signatures of van Hove
singularities that can enhance many-body interactions. Additionally, transport
measurements demonstrated that NbGe$_2$ exhibits superconductivity below 2K.
Overall, our comprehensive results provide the first concrete evidence that
NbGe$_2$ is a promising platform for investigating the interplay between
non-trivial band topology, possible Weyl fermions, van Hove singularities, and
superconductivity in chiral quantum materials.
