Hedgehog Spin-texture and Berry's Phase tuning in a Magnetic Topological Insulator
Su-Yang Xu, Madhab Neupane, Chang Liu +18
Understanding and control of spin degrees of freedom on the surfaces of topological materials are key to future applications as well as for realizing novel physics such as the axio…
A topological crystalline insulator (TCI) phase via topological phase transition and crystalline mirror symmetry
Su-Yang Xu, Chang Liu, Nasser Alidoust +18
A Z2 topological insulator protected by time-reversal symmetry is realized via spin-orbit interaction driven band inversion. For example, the topological phase in the Bi-Sb system…
Anomalous spin-momentum locked two-dimensional states in the vicinity of a topological phase transition
Su-Yang Xu, M. Neupane, Chang Liu +12
We perform spin-resolved and spin-integrated angle-resolved photoemission spectroscopy measurements on a series of compositions in the BiTl(S1-xSex)2 system, focusing on x-values i…
Surface and bulk Fermiology and band dispersion in non-centrosymmetric BiTeI
Gabriel Landolt, Sergey V. Eremeev, Yury M. Koroteev +11
BiTeI has a layered and non-centrosymmetric structure where strong spin-orbit interaction leads to a giant spin splitting in the bulk bands. Here we present high-resolution angle-r…
Three-Dimensional Spin Rotations at the Fermi Surface of a Strongly Spin-Orbit Coupled Surface System
Philipp Hoepfner, Joerg Schaefer, Andrzej Fleszar +8
The spin texture of the metallic two-dimensional electron system (root3 x root3)-Au/Ge(111) is revealed by fully three-dimensional spin-resolved photoemission, as well as by densit…
