Unveiling van Hove singularity modulation and fluctuated charge order in kagome superconductor via time-resolved ARPES
Yigui Zhong, Takeshi Suzuki, Hongxiong Liu +10
Kagome superconductor CsV3Sb5, which exhibits intertwined unconventional charge density wave (CDW) and superconductivity, has garnered significant attention recently. Despite exten…
Time- and angle-resolved photoemission spectroscopy with wavelength-tunable pump and extreme ultraviolet probe enabled by twin synchronized amplifiers
Takeshi Suzuki, Yigui Zhong, Kecheng Liu +3
We describe a setup for time- and angle-resolved photoemission spectroscopy with wavelength-tunable excitation and extreme ultraviolet probe. It is enabled by using the 10 kHz twin…
Photo-induced nonlinear band shift and valence transition in SmS
Yitong Chen, Takuto Nakamura, Hiroshi Watanabe +12
The photo-induced band structure variation of a rare-earth-based semiconductor, samarium monosulfide (SmS), was investigated using high-harmonic-generation laser-based time-resolve…
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…
Efficient Terahertz Harmonic Generation with Coherent Acceleration of Electrons in the Dirac Semimetal Cd3As2
Bing Cheng, Natsuki Kanda, Tatsuhiko N. Ikeda +7
We report strong terahertz (~10^12 Hz) high harmonic generation in thin films of Cd3As2, a three-dimensional Dirac semimetal at room temperature. The third harmonics is detectable…
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…
