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…
Direct observation of multiple conduction-band minima in high-performance thermoelectric SnSe
Mario Okawa, Yuka Akabane, Mizuki Maeda +14
We report time- and angle-resolved photoemission spectroscopy on SnSe which currently attracts great interest due to its extremely high thermoelectric performance. Laser-assisted p…
Photo-excitation band-structure engineering of 2H-NbSe probed by time- and angle-resolved photoemission spectroscopy
Mari Watanabe, Takeshi Suzuki, Takashi Someya +8
We investigated the nonequilibrium electronic structure of 2H-NbSe by time- and angle-resolved photoemission spectroscopy. We find that the band structure is distinctively modu…
Detecting electron-phonon couplings during photo-induced phase transition
Takeshi Suzuki, Yasushi Shinohara, Yangfan Lu +13
Photo-induced phase transitions have been intensively studied owing to the ability to control a material of interest in the ultrafast manner, which can induce exotic phases unable…
Photo-induced Superconducting State with Long-lived Disproportionate Band Filling in FeSe
Takeshi Suzuki, Takashi Someya, Takahiro Hashimoto +11
Photo-excitation is a very powerful way to instantaneously drive a material into a novel quantum state without any fabrication, and variable ultrafast techniques have been develope…
Ultrafast unbalanced electron distributions in quasicrystalline 30° twisted bilayer graphene
T. Suzuki, T. Iimori, S. J. Ahn +15
Layers of twisted bilayer graphene exhibit varieties of exotic quantum phenomena1-5. Today, the twist angle Θ has become an important degree of freedom for exploring novel states o…
Photo-induced semimetallic states realised in electron-hole coupled insulators
Kozo Okazaki, Yu Ogawa, Takeshi Suzuki +15
Using light to manipulate materials into desired states is one of the goals in condensed matter physics, since light control can provide ultrafast and environmentally-friendly phot…
Antiphase Fermi-surface modulations accompanying displacement excitation in a parent compound of iron-based superconductors
Kozo Okazaki, Hakuto Suzuki, Takeshi Suzuki +12
We investigate the transient electronic structure of BaFe2As2, a parent compound of iron-based superconductors, by time- and angle-resolved photoemission spectroscopy. In order to…
