Numerical study of transport through a single impurity in a spinful Tomonaga-Luttinger liquid
Yuji Hamamoto, Ken-Ichiro Imura, Takeo Kato
The single impurity problem in a spinful Tomonaga-Luttinger liquid is studied numerically using path-integral Monte Carlo methods. The advantage of our approach is that the system…
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…
Theory of Macroscopic Quantum Tunneling and Dissipation in High-Tc Josephson Junctions
Shiro Kawabata, Satoshi Kashiwaya, Yasuhiro Asano +3
We have investigated macroscopic quantum tunneling (MQT) in in-plane high-Tc superconductor Josephson junctions and the influence of the nodal-quasiparticle and the zero energy bou…
