Abstract Gamma‐ray glows are observational evidence of relativistic electron acceleration due to the electric field in thunderclouds. However, it is yet to be understood whether such relativistic electrons contribute to the initiation of lightning

Terahertz-field-induced polar charge order in electronic-type dielectrics

Autor: H. Yamakawa, T. Miyamoto, T. Morimoto, N. Takamura, S. Liang, H. Yoshimochi, T. Terashige, N. Kida, M. Suda, H. M. Yamamoto, H. Mori, K. Miyagawa, K. Kanoda, H. Okamoto

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-11 (2021)

Photoinduced phase transition is a central issue in the field of non-equilibrium quantum physics. Here, the authors demonstrate that a terahertz electric-field pulse changes a Mott insulator of an organic molecular compound to a macroscopically polar

Ionic to neutral conversion induced by resonant excitation of molecular vibrations coupled to intermolecular charge transfer

Autor: T. Morimoto, H. Suzuki, T. Otaki, N. Sono, N. Kida, T. Miyamoto, H. Okamoto

Publikováno v: Physical Review Research, Vol 3, Iss 4, p L042028 (2021)

In organic molecular compounds, intramolecular vibration is sometimes coupled with intermolecular charge transfer (CT). In such materials, vibrational excitation by a midinfrared (MIR) pulse causes collective intermolecular CTs that can be a route to

First experimental determination of the radiative-decay probability of the 31− state in 12C for estimating the triple alpha reaction rate in high temperature environments

Publikováno v: Physics Letters B, Vol 817, Iss , Pp 136283- (2021)

The triple alpha reaction is one of the most important reactions in the nuclear astrophysics. However, its reaction rate in high temperature environments at T9> 2 was still uncertain. One of the major origins of the uncertainty was that the radiative

Long-term stabilization of carrier envelope phases of mid-infrared pulses for the precise detection of phase-sensitive responses to electromagnetic waves

Autor: T. Yamakawa, N. Sono, T. Kitao, T. Morimoto, N. Kida, T. Miyamoto, H. Okamoto

Publikováno v: AIP Advances, Vol 10, Iss 2, Pp 025311-025311-7 (2020)

We report a high performance mid-infrared pump visible probe measurement system, which can measure phase-sensitive responses to a mid-infrared pulse along the oscillating electromagnetic field. In this system, the pump light is a phase-locked mid-inf

Probing ultrafast spin-relaxation and precession dynamics in a cuprate Mott insulator with seven-femtosecond optical pulses

Autor: T. Miyamoto, Y. Matsui, T. Terashige, T. Morimoto, N. Sono, H. Yada, S. Ishihara, Y. Watanabe, S. Adachi, T. Ito, K. Oka, A. Sawa, H. Okamoto

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-7 (2018)

Understanding the dynamics of cuprates following photoexcitation can provide insights into the complex coupling mechanisms that underlie their exotic equilibrium behaviour. Here the authors use pump-probe reflection spectroscopy to investigate the no
