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…
Nodeless electron pairing in CsVSb-derived kagome superconductors
Yigui Zhong, Jinjin Liu, Xianxin Wu +19
The newly discovered kagome superconductors represent a promising platform for investigating the interplay between band topology, electronic order, and lattice geometry. Despite ex…
Coexistence of bulk-nodal and surface-nodeless Cooper pairings in a superconducting Dirac semimetal
Xian P. Yang, Yigui Zhong, Sougata Mardanya +21
The interplay of nontrivial topology and superconductivity in condensed matter physics gives rise to exotic phenomena. However, materials are extremely rare where it is possible to…
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…
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…
Testing Electron-phonon Coupling for the Superconductivity in Kagome Metal
Yigui Zhong, Shaozhi Li, Hongxiong Liu +12
In crystalline materials, electron-phonon coupling (EPC) is a ubiquitous many-body interaction that drives conventional Bardeen-Cooper-Schrieffer superconductivity. Recently, in a…
