Real-space Obstruction in Quantum Spin Hall Insulators
Philipp Eck, Carmine Ortix, Armando Consiglio +6
The recently introduced classification of two-dimensional insulators in terms of topological crystalline invariants has been applied so far to "obstructed" atomic insulators charac…
Recipe for higher-order topology on the triangular lattice
Philipp Eck, Yuan Fang, Domenico Di Sante +2
We present a recipe for an electronic 2D higher order topological insulator (HOTI) on the triangular lattice that can be realized in a large family of materials. The essential ingr…
Interplay of Dirac nodes and Volkov-Pankratov surface states in compressively strained HgTe
David M. Mahler, Julian-Benedikt Mayer, Philipp Leubner +8
Preceded by the discovery of topological insulators, Dirac and Weyl semimetals have become a pivotal direction of research in contemporary condensed matter physics. While easily ac…
Custodial glide symmetry of quantum spin Hall edge modes in WTe monolayer
Seulgi Ok, Lukas Muechler, Domenico Di Sante +3
A monolayer of WTe has been shown to display quantum spin Hall (QSH) edge modes persisting up to 100~K in transport experiments. Based on density-functional theory calculations…
Robust spin-polarized midgap states at step edges of topological crystalline insulators
Paolo Sessi, Domenico Di Sante, Andrzej Szczerbakow +11
Topological crystalline insulators are materials in which the crystalline symmetry leads to topologically protected surface states with a chiral spin texture, rendering them potent…
