Possible observation of energy level quantization in an intrinsic Josephson junction
H. Kashiwaya, T. Matsumoto, S. Kashiwaya +5
Energy level quantization (ELQ) is studied to clarify the macroscopic quantum dynamics of the d-wave Josephson junction (JJ). The influences of the nodal quasiparticles of d-wave s…
Theory of Macroscopic Quantum Tunneling in High-T_c c-Axis Josephson Junctions
Takehito Yokoyama, Shiro Kawabata, Takeo Kato +1
We study macroscopic quantum tunneling (MQT) in c-axis twist Josephson junctions made of high-T_c superconductors in order to clarify the influence of the anisotropic order paramet…
Switching Dynamics of BiSrCaCuO Intrinsic Josephson junctions: Macroscopic Quantum Tunneling and Self-Heating Effect
H. Kashiwaya, T. Matsumoto, H. Shibata +5
The switching dynamics of current-biased BiSrCaCuO intrinsic Josephson junctions (IJJs) was studied to clarify the effect of d-wave superconductivity and…
Macroscopic quantum dynamics of pi-junctions with ferromagnetic insulators
Shiro Kawabata, Satoshi Kashiwaya, Yasuhiro Asano +2
We theoretically investigate the macroscopic quantum dynamics of a pi junction with a superconductor (S) and a multiferroic material or a ferromagnetic insulator (FI). By deriving…
