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…
Testing the Power-Law Hypothesis of the Inter-Conflict Interval
Hiroshi Okamoto, Iku Yoshimoto, Sota Kato +2
The severity of war, measured by battle deaths, follows a power-law distribution. Here, we demonstrate that power law also holds in the temporal aspects of interstate conflicts. A…
TEM at Millikelvin Temperatures: Observing and Utilizing Superconducting Qubits
Hiroshi Okamoto, Reza Firouzmandi, Ryosuke Miyamura +4
We present a case for developing a millikelvin-temperature transmission electron microscope (TEM). We start by reviewing known reasons for such development, then present new possib…
Biological implications of possible unattainability of comprehensive, molecular-resolution, real-time, volume imaging of the living cell
Hiroshi Okamoto
Despite the impressive advances in biological imaging, no imaging modality today generates, in a comprehensive manner, high-resolution images of crowded molecules working deep insi…
Visualization of ferroelectric domains in boracite using emission of terahertz radiation
Y. Kinoshita, N. Kida, M. Sotome +5
We report on the emission of terahertz radiation by irradiation of femtosecond laser pulses in non-centrosymmetric paraelectric and ferroelectric phases of CoBOI bor…
Terahertz radiation by optical rectification in a hydrogen-bonded organic molecular ferroelectric crystal, 2-phenylmalondialdehyde
W. Guan, N. Kida, M. Sotome +5
Terahertz radiation by optical rectification has been observed at room temperature in a hydrogen-bonded organic molecular ferroelectric crystal, 2-phenyl malondialdehyde (PhMDA). T…
