Topological materials discovery from crystal symmetry
Topological materials discovery has evolved at a rapid pace over the past 15 years following the identification of the first nonmagnetic topological insulators (TIs), topological crystalline insulators (TCIs) ...

Open AccessElectronic correlations and flattened band in magnetic Weyl semimetal candidate Co3Sn2S2
The interplay between electronic correlations and topological protection may offer a rich avenue for discovering emergent quantum phenomena in condensed matter. However, electronic correlations have so far bee...

Nodal-chain metals
A hitherto unrecognized type of fermionic excitation in metals is described, which forms a chain of connected loops in momentum space (a nodal chain) along which conduction and valence bands touch.

Type-II Weyl semimetals
A new type of topological semimetal is described, which contains so-called type-II Weyl fermions and has very different properties to standard Weyl semimetals, owing to the existence of an open Fermi surface r...
