Dirac lines and loop at the Fermi level in the time-reversal symmetry breaking superconductor LaNiGa2

Abstract

Topological superconducting systems are expected to exhibit a range of exotic physics which are particularly useful for application in quantum computing technologies. Here, the authors report the synthesis of LaNiGa2 which exhibits both topological and superconducting features originating from its nonsymmorphic crystal structure.
