Autor: Yoichi Okimoto, Peiyu Xia, Jiro Itatani, Haruka Matsushima, Tadahiko Ishikawa, Shin-ya Koshihara, Sachio Horiuchi

Publikováno v: APL Materials, Vol 10, Iss 9, Pp 090702-090702-8 (2022)

We investigated the ultrafast photo-response of a ferroelectric co-crystal of Hdppz–Hca composed of protonated 2,3-di (2-pyridinyl)pyrazine (Hdppz) and deprotonated chloranilic acid (Hca). Whereas the intermolecular proton transfer triggers the fer

Raschke, Eckart Rühl, Annika Schlander, Markus Gallei, Lennart Seiffert, Thomas Fennel, Boris Bergues, Matthias F. Kling

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-7 (2019)

Understanding light-matter interaction is important for the control of energy and charge transfer at the fundamental level. Here the authors spatially resolve proton generation in laser-induced dissociative ionization of ethanol and water on SiO2 nan

Real-time observation of the Woodward-Hoffmann rule for 1,3-cyclohexadiene by femtosecond soft X-ray transient absorption

Publikováno v: Physical chemistry chemical physics. 25(12):8497-8506

The stereochemistry of pericyclic reactions is explained by orbital symmetry conservation, referred to as the Woodward-Hoffmann (WH) rule. Although this rule has been verified using the structures of reactants and products, the temporal evolution of

Photo-induced semimetallic states realised in electron–hole coupled insulators

Autor: Kozo Okazaki, Yu Ogawa, Takeshi Suzuki, Takashi Yamamoto, Takashi Someya, Shoya Michimae, Mari Watanabe, Yangfan Lu, Minoru Nohara, Hidenori Takagi, Naoyuki Katayama, Hiroshi Sawa, Masami Fujisawa, Teruto Kanai, Nobuhisa Ishii, Jiro Itatani, Takashi Mizokawa, Shik Shin

Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-6 (2018)

Ultrafast light pulses can manipulate and probe materials faster than relaxation timescales, leading to new electronic states and insights into equilibrium properties. Okazaki et al. use the properties of photo-induced metallic states to investigate

Attosecond electronic dynamics of core-excited states of N_{2}O in the soft x-ray region

Autor: Nariyuki Saito, Nicolas Douguet, Hiroki Sannohe, Nobuhisa Ishii, Teruto Kanai, Yi Wu, Andrew Chew, Seunghwoi Han, Barry I. Schneider, Jeppe Olsen, Luca Argenti, Zenghu Chang, Jiro Itatani

Publikováno v: Physical Review Research, Vol 3, Iss 4, p 043222 (2021)

We present a combined experimental and theoretical study of the transient absorption spectroscopy of N_{2}O at the N K edge (400 eV) by employing an attosecond soft x-ray pulse and an overlapping intense femtosecond infrared pulse. Our experiment dem

High-order harmonic generation from hybrid organic–inorganic perovskite thin films

Autor: Hideki Hirori, Peiyu Xia, Yasushi Shinohara, Tomohito Otobe, Yasuyuki Sanari, Hirokazu Tahara, Nobuhisa Ishii, Jiro Itatani, Kenichi L. Ishikawa, Tomoko Aharen, Masashi Ozaki, Atsushi Wakamiya, Yoshihiko Kanemitsu

Publikováno v: APL Materials, Vol 7, Iss 4, Pp 041107-041107-4 (2019)

The generation of high-order harmonics from hybrid organic–inorganic perovskites (HOIPs) is demonstrated by the excitation with a strong mid-infrared laser pulse. We prepare three types of HOIP polycrystalline thin film samples by solution processe
