BCS-BEC crossover and superconductor-insulator transition in Hopf-linked Graphene layers: Hopfene
We have proposed a topological carbon allotrope, named Hopfene, which has three-dimensional (3 D ) arrays of Hopf-links to bind 2 D Graphene layers both horizontally and vertically without forming strong σ bonds between layers. Tight-binding calculations show unique band structures of this crystal,...
