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…
Moiré superlattices of antimonene on a Bi(111) substrate with van Hove singularity and Rashba-type spin polarization
Tomonori Nakamura, Yitao Chen, Ryohei Nemoto +9
Moiré superlattices consisting of two-dimensional materials have attracted immense attention because of emergent phenomena such as flat band-induced Mott insulating states and unco…
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…
Broken Screw Rotational Symmetry in the Near-Surface Electronic Structure of -Stacked Crystals
Hiroaki Tanaka, Shota Okazaki, Masaru Kobayashi +10
We investigate the electronic structure of - and - by angle-resolved photoemission spectroscopy (ARPES) and photoemission intensity cal…
Time-, spin-, and angle-resolved photoemission spectroscopy with a 1-MHz 10.7-eV pulse laser
Kaishu Kawaguchi, Kenta Kuroda, Z. Zhao +12
We describe a setup of time-, spin-, and angle-resolved photoemission spectroscopy (tr-SARPES) employing a 10.7-eV (=115.6 nm) pulse laser at 1-MHz repetition rate as a probe ph…
Spin-polarized saddle points in the topological surface states of the elemental Bismuth revealed by a pump-probe spin-resolved ARPES
Yuto Fukushima, Kaishu Kawaguchi, Kenta Kuroda +11
We use a pump-probe, spin-, and angle-resolved photoemission spectroscopy (ARPES) with a 10.7 eV laser accessible up to the Brillouin zone edge, and reveal for the first time the e…
Direct observation of topological surface state in the topological superconductor 2M-WS2
Soohyun Cho, Soonsang Huh, Yuqiang Fang +15
The quantum spin Hall (QSH) effect has attracted extensive research interest because of the potential applications in spintronics and quantum computing, which is attributable to tw…
