Topological nodal-line fermions in spin-orbit metal PbTaSe2
Topological semimetals can support one-dimensional Fermi lines or zero-dimensional Weyl points in momentum space, where the valence and conduction bands touch. While the degeneracy points in WeylExpand

Symmetries, dimensions and topological insulators: the mechanism behind the face of the Bott clock
We provide an account of some of the mathematics of Bott periodicity and the Atiyah, Bott, Shapiro construction. We apply these ideas to understanding the twisted bundles of electron bands thatExpand

Drumhead Surface States and Topological Nodal-Line Fermions in TlTaSe2
A topological nodal-line semimetal is a new condensed matter state with one-dimensional bulk nodal lines and two-dimensional drumhead surface bands. Based on first-principles calculations and ourExpand

Strongly interacting Majorana fermions
Interesting phases of quantum matter often arise when the constituent particles---electrons in solids---interact strongly. Such strongly interacting systems are, however, quite rare and occur only inExpand

Classification of reflection-symmetry-protected topological semimetals and nodal superconductors
While the topological classification of insulators, semimetals, and superconductors in terms of nonspatial symmetries is well understood, less is known about topological states protected byExpand

Classification of topological insulators and superconductors in the presence of reflection symmetry
We discuss a topological classification of insulators and superconductors in the presence of both (non-spatial) discrete symmetries in the Altland-Zirnbauer classification and spatial reflectionExpand

Fermion doubling theorems in 2D non-Hermitian systems
The fermion doubling theorem plays a pivotal role in Hermitian topological materials. It states, for example, that Weyl points must come in pairs in three-dimensional semimetals. Here, we present anExpand

Classification of crystalline topological semimetals with an application to Na3Bi
Topological phases can not only be protected by internal symmetries (e.g., time-reversal symmetry), but also by crystalline symmetries, such as reflection or rotation symmetry. Recently a completeExpand

Conductance of a superconducting Coulomb-blockaded Majorana nanowire
In the presence of an applied magnetic field introducing Zeeman spin splitting, a superconducting (SC) proximitized one-dimensional (1D) nanowire with spin-orbit coupling can pass through aExpand
