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…

Melting of excitonic insulator phase by an intense terahertz pulse in Ta $_{2}$ NiSe $_{5}$

Naoki Takamura, Tatsuya Miyamoto, Ryohei Ikeda +9

In this study, the optical response to a terahertz pulse was investigated in the transition metal chalcogenide Ta $_{2}$ NiSe $_{5}$ , a candidate excitonic insulator. First, by irradiatin…

Photoexcitation of a polarization-inverted domain from the charge-ordered ferroelectric ground state of (TMTTF) $_{2}$ PF $_{6}$

T. Yamaguchi, K. Asada, H. Yamakawa +5

We theoretically revealed that a weak photoexcitation achieves the electric polarization-inversion with approximately $18%$ of all the charges, which was interpreted as a superimp…
