Symmetry breaking driven by petahertz electron acceleration in a centrosymmetric organic superconductor
Y. Kawakami, T. Amano, H. Ohashi +10
Charge acceleration during an intense light field application to solids attracts much attention as elementary processes in high-harmonic generation and photoelectron emission [1-7]…
Strong light-field effects driven by nearly single-cycle 7-fs light field in correlated organic conductors
Yohei Kawakami, Hirotake Itoh, Kenji Yonemitsu +1
We have demonstrated transient charge localization effects with a driving high-frequency field of 7-fs, 1.5-cycle near infrared light in correlated organic conductors. In a layered…
Non-linear charge oscillation driven by a single-cycle light-field in an organic superconductor
Y. Kawakami, T. Amano, Y. Yoneyama +11
Intense light-field application to solids produces enormous/ultrafast non-linear phenomena such as high-harmonic generations 1, 2 and attosecond charge dynamics 3, 4. They are dist…
Polarization selectivity of charge localization induced by 7-fs nearly single-cycle light-field in an organic metal
Y. Kawakami, Y. Yoneyama, T. Amano +9
Polarization selectivity of light-field-induced charge localization was investigated in an organic metal alpha-(BEDT-TTF)2I3 with a triangular lattice. Dependences of transient ref…
Ultrafast response of plasma-like reflectivity edge in (TMTTF)2AsF6 driven by 7-fs, 1.5-cycle strong-light field
Y. Naitoh, Y. Kawakami, T. Ishikawa +9
The strong light-field effect of (TMTTF)2AsF6 was investigated utilizing 1.5-cycle, 7-fs infrared pulses. The ultarfast (20 fs) and large (40%) response of the plasma-like reflecti…
Optical freezing of charge motion in an organic conductor
Takahiro Ishikawa, Yuto Sagae, Yota Naitoh +10
Dynamical localization, i.e., reduction of the intersite electronic transfer integral t by an alternating electric field, E(omega) , is a promising strategy for controlling strongl…
