Delicate topology protected by rotation symmetry: Crystalline Hopf insulators and beyond
Aleksandra Nelson, Titus Neupert, A. Alexandradinata +1
Pontrjagin's seminal topological classification of two-band Hamiltonians in three momentum dimensions is hereby enriched with the inclusion of a crystallographic rotational symmetr…
Multicellularity of delicate topological insulators
Aleksandra Nelson, Titus Neupert, Tomáš Bzdušek +1
Being Wannierizable is not the end of the story for topological insulators. We introduce a family of topological insulators that would be considered trivial in the paradigm set by…
Teleportation of Berry curvature on the surface of a Hopf insulator
A. Alexandradinata, Aleksandra Nelson, Alexey A. Soluyanov
The existing paradigm for topological insulators asserts that an energy gap separates conduction and valence bands with opposite topological invariants. Here, we propose that \text…
