Ultrafast Control of Crystal Structure in a Topological Charge-Density-Wave Material
Takeshi Suzuki, Yuya Kubota, Natsuki Mitsuishi +15
Optical control of crystal structures is a promising route to change physical properties including topological nature of a targeting material. Time-resolved X-ray diffraction measu…
Phase-resolved frequency-domain analysis of the photoemission spectra for photoexcited 1T-TaS2 in the Mott insulating charge density wave state
Q. -H. Ren, T. Suzuki, T. Kanai +3
We investigate the nonequilibrium electronic structure of 1T-TaS2 by time- and angle-resolved photoemission spectroscopy. We observe that strong photoexcitation induces the collaps…
HHG-laser-based time- and angle-resolved photoemission spectroscopy of quantum materials
Takeshi Suzuki, Shik Shin, Kozo Okazaki
Time- and angle-resolved photoemission spectroscopy has played an important role in revealing the non-equilibrium electronic structures of solid-state materials. The implementation…
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…
Role of electron-electron and electron-phonon interaction effect in the optical conductivity of VO2
K. Okazaki, S. Sugai, Y. Muraoka +1
We have investigated the charge dynamics of VO2 by optical reflectivity measurements. Optical conductivity clearly shows a metal-insulator transition. In the metallic phase, a broa…
