Emergence of topological semimetals in gap closing in semiconductors without inversion symmetry
Shuichi Murakami, Motoaki Hirayama, Ryo Okugawa +1
A band gap for electronic states in crystals governs various properties of solids, such as transport, optical and magnetic properties. Its estimation and control have been an impor…

Topological Dirac Nodal Lines and Surface Charges in fcc Alkaline Earth Metals
Motoaki Hirayama, Ryo Okugawa, Takashi Miyake +1
In nodal-line semimetals, the gaps close along loops in space, which are not at high-symmetry points. Typical mechanisms for the emergence of nodal lines involve mirror s…
