Material realization of spinless, covalent-type Dirac semimetals in three dimensions
Yuki Tanaka, Rinsuke Yamada, Manabu Sato +2
Realization of a three-dimensional (3D) analogue of graphene has been a central challenge in topological materials science. Graphene is stabilized by covalent bonding unlike conven…

Three-dimensional spinless Euler insulators with rotational symmetry
Manabu Sato, Shingo Kobayashi, Motoaki Hirayama +1
The Euler class is a -valued topological invariant that characterizes a pair of real bands in a two-dimensional Brillouin zone. One of the symmetries that permits its d…

C NMR Study on Zero-Gap State in the Organic Conductor -(BEDT-TTF)I under Pressure
K. Miyagawa, M. Hirayama, M. Tamura +1
We present the results of our C NMR study of the quasi-two-dimensional organic conductor -(BEDT-TTF)I under pressure, which is suggested to be a zero-gap conduc…
