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…

Piezoelectric Transition in a Nonpyroelectric Gyroidal Metal-Organic Framework
Shunsuke Kitou, Hajime Ishikawa, Yusuke Tokunaga +8
Among the thirty-two crystallographic point groups, 432 is the only one that lacks an inversion center but does not exhibit piezoelectricity. A gyroidal structure belongs to point…
