High-harmonic generation during ultrafast melting of a Mott insulating state
Ryohei Ikeda, Yuta Murakami, Daiki Sakai +3
Solids in an intense laser field show high-harmonic generation (HHG), which can provide information on carrier dynamics and band structures in weakly correlated systems. In strongl…

Photo-induced phase transition on black samarium monosulfide
Hiroshi Watanabe, Yusuke Takeno, Yusuke Negoro +14
To investigate the role of the excitons for the origin of the pressure-induced phase transition (BGT) from the black-colored insulator (BI) to the golden-yellow-colored metal (GM)…

Melting of excitonic insulator phase by an intense terahertz pulse in TaNiSe
Naoki Takamura, Tatsuya Miyamoto, Ryohei Ikeda +9
In this study, the optical response to a terahertz pulse was investigated in the transition metal chalcogenide TaNiSe, a candidate excitonic insulator. First, by irradiatin…
