Gapped energy spectra around the Dirac node at the surface of a 3D topological insulator in the presence of the time-reversal symmetry
Tetsuro Habe, Yasuhiro Asano
We discuss the excitation spectra around the Dirac node on a surface of a three-dimensional topological insulator. By using the diagrammatic expansion, we show that the coupling of…
Bulk-boundary correspondence in Josephson Junctions
Jeongmin Yoo, Tetsuro Habe, Yasuhiro Asano
We discuss bound states appearing at the interface between two different superconductors characterized by different nontrivial topological numbers such as one-dimensional winding n…
Interface Metallic States between a Topological Insulator and a Ferromagnetic Insulator
Tetsuro Habe, Yasuhiro Asano
We study electronic structures at an interface between a topological insulator and a ferromagnetic insulator by using three-dimensional two-band model. In usual ferromagnetic insul…
Anomalous Surface Impedance in a Normal-metal/Superconductor Junction with a Spin-active Interface
Yasuhiro Asano, Masahiro Ozaki, Tetsuro Habe +2
We discuss the surface impedance (Z=R-iX) of a normal-metal/superconductor proximity structure taking into account the spin-dependent potential at the junction interface. Because o…
