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…
Time-resolved synchronization analysis of stacked intrinsic Josephson junctions of a cuprate superconductor with frequency-modulated terahertz radiation spectra
Masashi Miyamoto, Keisuke Mizoguchi, Ryota Kobayashi +3
Terahertz radiation from intrinsic Josephson junctions (IJJs) provides an ideal platform to study the synchronization of a macro…
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…
Wide-band frequency modulation of a terahertz intrinsic Josephson junction emitter of a cuprate superconductor
M. Miyamoto, R. Kobayashi, G. Kuwano +2
Communication using terahertz (~10^12 Hz) electromagnetic waves is critical for developing 6th-generation wireless network infrastructures. Conflictions between stable radiation an…
Spontaneous frequency shift and phase delay of coupled terahertz radiations mediated by the Josephson plasmon in a cuprate superconductor
R. Kobayashi, K. Hayama, S. Fujita +2
We examine coupling interactions used to synchronize macroscopic Josephson oscillations induced in intrinsic Josephson junction (IJJ) mesa stacks made of a Bi2212 single crystal. S…
THz emission from a Bi2Sr2CaCu2O8+δ cross-whisker junction
Yoshito Saito, Shintaro Adachi, Ryo Matsumoto +7
Cuprate superconductor Bi2Sr2CaCu2O8+δ (BSCCO) has been a promising candidate of a coherent, continuous, and compact THz light source owing to its intrinsic Josephson junction insi…
