Extended strange metal regime in a pure nematic quantum critical superconductor
Kousuke Ishida, Kiyotaka Mukasa, Shusaku Imajo +12
High-temperature superconductivity often emerges from a strange metallic state, where the electrical resistivity exhibits a linear-in-temperature dependence over an anomalously ext…
Diamond quantum-sensing platform with integrated boron-doped diamond microwave antenna and thermometer
Masahiro Ohkuma, Ryo Matsumoto, Shintaro Adachi +5
Wide-field nitrogen-vacancy (NV) magnetic imaging at cryogenic temperatures requires microwave excitation and reliable knowledge of the temperature near the sensing region. Here, w…
Discriminating superconducting fluctuations from the pseudogap in BiSrCaCuO: A magnetotransport study
Shunpei Yamaguchi, Nae Sasaki, Shintaro Adachi +13
Understanding the normal state is essential for uncovering the mechanism of high- superconductivity. We investigate magnetotransport in BiSrCaCuO and Bi$_2…
Probing the Meissner effect in single crystals of via wide-field quantum microscopy under high pressure
Masahiro Ohkuma, Ryo Matsumoto, Shintaro Adachi +5
We investigated the pressure dependence of the superconducting transition temperature () in optimally doped BiSrCaCuO (Bi-2223) single crystals…
Proximity-Induced Nodal Metal in an Extremely Underdoped CuO Plane in Triple-Layer Cuprates
Shin-ichiro Ideta, Shintaro Adachi, Takashi Noji +15
ARPES studies have established that the high- cuprates with single and double CuO layers evolve from the Mott insulator to the pseudogap state with a Fermi arc, on which t…
Topology meets time-reversal symmetry breaking in FeSeTe superconductor
M. Roppongi, Y. Cai, K. Ogawa +21
Time-reversal symmetry breaking (TRSB) in magnetic topological insulators induces a Dirac gap in the topological surface state (TSS), leading to exotic phenomena such as the quantu…
Correlation between and the Pseudogap Observed in the Optical Spectra of High Superconducting Cuprates
Setsuko Tajima, Yuhta Itoh, Katsuya Mizutamari +6
We studied the temperature dependences of the optical spectra for optimally and underdoped BiSrCaCuO single crystals. Similarly to the other cuprates' case…
Effects of vortex and antivortex excitations in underdoped BiSrCaCuO bulk single crystals
Takao Watanabe, Kenta Kosugi, Nae Sasaki +5
The observance of vortex and anti-vortex effects in bulk crystals can prove the existence of phase-disordered superconductivity in the bulk. To gain insights into the mechanisms th…
Enhanced superconducting pairing strength near a nonmagnetic nematic quantum critical point
K. Mukasa, K. Ishida, S. Imajo +14
The quest for high-temperature superconductivity at ambient pressure is a central issue in physics. In this regard, the relationship between unconventional superconductivity and th…
Role of the inner copper-oxide plane in interlayer Josephson effects in multi-layered cuprate superconductors
Y. Nomura, R. Okamoto, T. Mizuno +4
We find systematic signatures suggesting a different superconducting nature for a triple-layered cuprate BiSrCaCuO with respect to a double-layer through t…
Single-crystal growth of underdoped Bi-2223
S. Adachi, T. Usui, K. Takahashi +10
To investigate the origin of the enhanced Tc ({\approx} 110 K) of the trilayer cuprate superconductor Bi2Sr2Ca2Cu3O10+δ (Bi-2223), its underdoped single crystals are a critical req…
Effects of Annealing under Tellurium Vapor for FeTeSe Single Crystals
Yuta Koshika, Tomohiro Usui, Shintaro Adachi +4
In this study, the effects of annealing under tellurium vapor have been investigated for FeTeSe single crystals. The as-grown crystal is not superconductin…
