Lattice deformation on flat-band modulation in 3D Hopf-linked carbon allotrope: Hopfene
Isao Tomita, Shinichi Saito
Flat bands form in a 3D Hopf-linked graphene crystal or a 3D carbon allotrope named Hopfene, which qualitatively differ from bands of only graphenes. This paper discusses carbon-he…

Electronic and structural properties of 3D Hopf-linked carbon allotrope: Hopfene
Isao Tomita, Shinichi Saito
Electronic and structural properties of a 3D carbon allotrope made of Hopf-linked graphenes, which we call a Hopfene - a type of topological crystal, are examined by semi-empirical…

Dirac and Weyl Fermions in 3D Hopf-linked Honeycomb Lattices: Hopfene
Shinichi Saito, Isao Tomita
Carbon allotropes such as diamond, nano-tube, Fullerene, and Graphene, have unique lattice symmetries of crystal lattice, but these are topologically trivial. We have proposed a to…
