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…
