Topological nature of step edge states on the surface of topological crystalline insulator PbSnSe
Davide Iaia, Chang-Yan Wang, Yulia Maximenko +5
In addition to novel surface states, topological insulators can also exhibit robust gapless states at crystalline defects. Step edges constitute a class of common defects on the su…

Searching for topological Fermi arcs via quasiparticle interference on a type-II Weyl semimetal MoTe
Davide Iaia, Guoqing Chang, Tay-Rong Chang +5
Weyl semimetals display a novel topological phase of matter where the Weyl nodes emerge in pairs of opposite chirality and can be seen as either a source or a sink of Berry curvatu…
