Violation of emergent rotational symmetry in the hexagonal Kagome superconductor CsV 3 Sb 5
Autor: Kazumi Fukushima, Keito Obata, Soichiro Yamane, Yajian Hu, Yongkai Li, Yugui Yao, Zhiwei Wang, Yoshiteru Maeno, Shingo Yonezawa
Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-9 (2024)
Abstract Superconductivity is caused by electron pairs that are canonically isotropic, whereas some exotic superconductors are known to exhibit non-trivial anisotropy stemming from unconventional pairings. However, superconductors with hexagonal symm

Autor: Muhammad Shahbaz Anwar, Taketomo Nakamura, Ryosuke Ishiguro, Shafaq Arif, Jason W. A. Robinson, Shingo Yonezawa, Manfred Sigrist, Yoshiteru Maeno
Publikováno v: Communications Physics, Vol 6, Iss 1, Pp 1-8 (2023)
Abstract Non-reciprocal electronic transport in a material occurs if both time reversal and inversion symmetries are broken. The superconducting diode effect (SDE) is an exotic manifestation of this type of behavior where the critical current for pos

Spacetime-emergent ring toward tabletop quantum gravity experiments
Autor: Koji Hashimoto, Daichi Takeda, Koichiro Tanaka, Shingo Yonezawa
Publikováno v: Physical Review Research, Vol 5, Iss 2, p 023168 (2023)
We propose a way to discover, in tabletop experiments, spacetime-emergent materials, that is, materials holographically dual to higher-dimensional quantum gravity systems under the AdS/CFT. The emergence of the holographic spacetime is verified by a

Uniaxial-strain control of nematic superconductivity in Sr x Bi2Se3
Autor: Ivan Kostylev, Shingo Yonezawa, Zhiwei Wang, Yoichi Ando, Yoshiteru Maeno
Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-8 (2020)
Nematic superconductors, exhibiting rotational-symmetry breaking, can form domains; a counterpart of common magnetic domains. Here, the authors report control of nematic superconductivity and their domains of Sr x Bi2Se3 by uniaxial deformation, a st

Superconductivity in the antiperovskite Dirac-metal oxide Sr3−xSnO
Autor: Mohamed Oudah, Atsutoshi Ikeda, Jan Niklas Hausmann, Shingo Yonezawa, Toshiyuki Fukumoto, Shingo Kobayashi, Masatoshi Sato, Yoshiteru Maeno
Publikováno v: Nature Communications, Vol 7, Iss 1, Pp 1-6 (2016)
Superconductivity has not been observed in any antiperovskite oxide up to now. Here Oudahet al. report superconducting transition around 5 K in antiperovskite oxide Sr3−xSnO, making it a new class of oxide superconductors.
