Stanene is a topological insulator comprised of atoms typically arranged in a similar pattern to those inside graphene. Stanene films have been found to be promising for the realization of numerous intriguing physics phases, ...
Topological states of matter are phases of matter that go beyond the Landau symmetry-breaking theory, which are characterized by topological invariants and topological edge states. Physicist David J. Thouless, in collaboration ...
Insulators that are conducting at their edges hold promise for interesting technological applications. However, until now their characteristics have not been fully understood. Physicists at Goethe University have now modelled ...
