Generation of an anomalous linearly dispersing spin-polarized band in Bi-based topological insulators
Matthias Kronseder, Thomas Mayer, Jan Minár +11
We report the generation of an anomalous linearly dispersing, spin-polarized band in Bi-based topological insulator (TI) thin films, induced by soft Ar-ion bombardment followed by…
Kramers nodal lines in intercalated TaS superconductors
Yichen Zhang, Yuxiang Gao, Aki Pulkkinen +24
Kramers degeneracy is one fundamental embodiment of the quantum mechanical nature of particles with half-integer spin under time reversal symmetry. Under the chiral and noncentrosy…
Revealing electronic correlations in YNiBC using photoemission spectroscopy
Aki Pulkkinen, Geoffroy Kremer, Vladimir N. Strocov +3
We present a combined density functional theory (DFT), one-step model of photoemission, and soft x-ray angle-resolved photoemission spectroscopy (SX-ARPES) study of the electronic…
Reexamining Circular Dichroism in Photoemission From a Topological Insulator
Ittai Sidilkover, Yun Yen, Sunil Wilfred D'Souza +10
The orbital angular momentum (OAM) of electron states is an essential ingredient for topological and quantum geometric quantities in solids. For example, Dirac surface states with…
