Ultrafast decoupling of quasiparticles and spin fluctuations in superconducting cuprates
Yuto Taniguchi, Ryo Kato, Tatsuya Amano +10
Understanding how quasiparticles are generated following a rapid quench of superconductivity in high-Tc cuprates is a key unresolved problem in nonequilibrium superconductivity. He…
Current-induced successive structural phase transitions beyond thermal equilibrium in single-crystal VO2
Shunsuke Kitou, Akitoshi Nakano, Masato Imaizumi +5
Nonequilibrium systems driven by external energy sources host unexplored physics; yet phase transitions beyond thermal equilibrium remain elusive. Here, we demonstrate that electri…
Anisotropic Optical Conductivity Accompanied by a Small Energy Gap in One-Dimensional Thermoelectric Telluride Ta4SiTe4
Fumiya Matsunaga, Yoshihiko Okamoto, Yasunori Yokoyama +7
We investigated the optical properties of single crystals of one-dimensional telluride Ta4SiTe4, which shows high thermoelectric performance below room temperature. Optical conduct…
Regular-Triangle Trimer and Charge Order Preserving the Anderson Condition in the Pyrochlore Structure of CsWO
Yoshihiko Okamoto, Haruki Amano, Naoyuki Katayama +14
Since the discovery of the Verwey transition in magnetite, transition metal compounds with pyrochlore structures have been intensively studied as a platform for realizing remarkabl…
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…
Phonon-Spectrum Narrowing Induced by Ultrafast Charge Fluctuation in an Organic Dimer Mott Insulator
K. Itoh, H. Itoh, S. Saito +7
We have observed the characteristic temperature dependence of the intermolecular phonon spectrum in the organic dimer Mott insulator kappa-(ET)2Cu2(CN)3 exhibiting a dielectric ano…
