Experimental observation of topological Fermi arcs in type-II Weyl semimetal MoTe2
Observations of topological surface states provide strong evidence that MoTe2 is a type-II Weyl semimetal, hosting Weyl fermions that have no counterpart in high-energy physics.

Gaps induced by inversion symmetry breaking and second-generation Dirac cones in graphene/hexagonal boron nitride
Images of the second-generation Dirac cones that form when graphene is placed on hexagonal boron nitride show the potential of using superlattices to engineer the electronic band structure of van der Waals het...

Fully gapped topological surface states in Bi2Se3 films induced by a d-wave high-temperature superconductor
By growing a topological insulator on top of a high-temperature superconducting substrate it is possible to induce superconductivity in the surface states of the topological insulator. Moreover, the pairing sy...
