Criticality of the metal-topological insulator transition driven by disorder
Ai Yamakage, Kentaro Nomura, Ken-Ichiro Imura +1
Employing scaling analysis of the localization length, we deduce the critical exponent of the metal-topological insulator (TI) transitions induced by disorder. The obtained exponen…
Bulk electronic state of superconducting topological insulator
Tatsuki Hashimoto, Keiji Yada, Ai Yamakage +2
We study electronic properties of a superconducting topological insulator whose parent material is a topological insulator. We calculate the temperature dependence of the specific…
Anomalous Josephson current in superconducting topological insulator
Ai Yamakage, Masatoshi Sato, Keiji Yada +2
We investigate the effect of helical Majorana fermions at the surface of superconducting topological insulators (STI) on the Josephson current by referring to possible pairing stat…
Theory of tunneling spectroscopy for chiral topological superconductors
Akihiro Ii, Ai Yamakage, Keiji Yada +2
We study the charge conductance of an interface between a normal metal and a superconducting quantum anomalous Hall system, based on the recursive Green's function. The angle resol…
