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…
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…
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…
Highly superlinear photogalvanic effects in (BiSb)(TeSe): Probing 3D topological insulator surface states at room temperature
Sergey N. Danilov, Leonid E. Golub, Thomas Mayer +8
We report on the observation of complex nonlinear intensity dependence of the circular and linear photogalvanic currents induced by infrared radiation in compensated (BiSb$…
Momentum resolved spin dynamics of bulk and surface excited states in the topological insulator
C. Cacho, A. Crepaldi, M. Battiato +16
The prospective of optically inducing a spin polarized current for spintronic devices has generated a vast interest in the out-of-equilibrium electronic and spin structure of topol…
