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…
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…
A robust weak topological insulator in a bismuth halide Bi4Br2I2
Ryo Noguchi, Masaru Kobayashi, Kaishu Kawaguchi +11
We apply a topological material design concept for selecting a bulk topology of 3D crystals by different van-der-Waals stacking of 2D topological insulator layers, and find a bismu…
Semiconducting Electronic Structure of the Ferromagnetic Spinel Revealed by Soft-X-Ray Angle-Resolved Photoemission Spectroscopy
Hiroaki Tanaka, Andrei V. Telegin, Yurii P. Sukhorukov +12
We study the electronic structure of the ferromagnetic spinel by soft-x-ray angle-resolved photoemission spectroscopy (SX-ARPES) and first-p…
SPADExp: A photoemission angular distribution simulator directly linked to first-principles calculations
Hiroaki Tanaka, Kenta Kuroda, Tomohiro Matsushita
We develop a software package SPADExp (simulator of photoemission angular distribution for experiments) to calculate the photoemission angular distribution (PAD), which is the mome…
Large anomalous Hall effect induced by weak ferromagnetism in the noncentrosymmetric antiferromagnet
Hiroaki Tanaka, Shota Okazaki, Kenta Kuroda +13
We study the mechanism of the exceptionally large anomalous Hall effect (AHE) in the noncentrosymmetric antiferromagnet by angle-resolved pho…
Visualization of the strain-induced topological phase transition in a quasi-one-dimensional superconductor TaSe3
Chun Lin, Masayuki Ochi, Ryo Noguchi +18
Control of the phase transition from topological to normal insulators can allow for an on/off switching of spin current. While topological phase transitions have been realized by e…
Material design with the van der Waals stacking of bismuth-halide chains realizing a higher-order topological insulator
Ryo Noguchi, Masaru Kobayashi, Zhanzhi Jiang +28
The van der Waals (vdW) materials with low dimensions have been extensively studied as a platform to generate exotic quantum properties. Advancing this view, a great deal of attent…
Three-dimensional electronic structure in ferromagnetic with breathing kagome bilayers
Hiroaki Tanaka, Yuita Fujisawa, Kenta Kuroda +9
A large anomalous Hall effect (AHE) has been observed in ferromagnetic with breathing kagome bilayers. To understand the underlying mechanism for this,…
