Direct observation of a spin-polarized surface Dirac gap in the antiferromagnetic topological insulator NdBi
Yuto Fukushima, Hiroyuki S. Suzuki, Masayuki Ochi +15
A gapped Dirac cone in antiferromagnetic topological insulators (AFM-TIs) is essential for realizing the quantized anomalous Hall effect, yet its intrinsic magnitude remains contro…

Photoemission angular distribution beyond the single wavevector description of photoelectron final states
Hiroaki Tanaka, Shota Okazaki, Yuto Fukushima +9
We develop a simulation procedure for angle-resolved photoemission spectroscopy (ARPES), where a photoelectron wave function is set to be an outgoing plane wave in a vacuum associa…
