Spectroscopic signatures of Kohn anomaly in a topological crystalline insulator
Jingwen Li, Arpita Dutta, Kush Saha +4
Topological crystalline insulators extend the concept of topological insulators by hosting surface states protected by crystallographic symmetry. Their topological phase transition…
Probing chiral symmetry with a topological domain wall sensor
Glenn Wagner, Titus Neupert, Ronny Thomale +5
Chiral symmetry is a fundamental property with profound implications for the properties of elementary particles, that implies a spectral symmetry (i.e. E => -E ) in their dispersio…
Interaction effects in a 1D flat band at a topological crystalline step edge
Glenn Wagner, Souvik Das, Johannes Jung +11
Step edges of topological crystalline insulators can be viewed as predecessors of higher-order topology, as they embody one-dimensional edge channels embedded in an effective three…

Johannes Jung, Artem Odobesko, Robin Boshuis +3
The interaction of spin-polarized one-dimensional (1D) topological edge modes localized along single-atomic steps of the topological crystalline insulator …
Electron-phonon coupling and a resonant-like optical observation of a band inversion in topological crystalline insulator PbSnSe
Mariusz Woźny, Wojciech Szuszkiewicz, Mateusz Dyksik +5
The optical reflectivity of PbSnSe and PbSnSe solid solutions was measured in the THz spectral region energetically corresponding to bulk opti…

Experimental evidence for topological surface states wrapping around bulk SnTe crystal
K. Dybko, M. Szot, A. Szczerbakow +6
We demonstrate that the metallic topological surface states wrap on all sides the 3D topological crystalline insulator SnTe. This is achieved by studying oscillatory quantum magnet…
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…
