Effect of Fermi surface evolution on superconducting gap in superconducting topological insulator
Tatsuki Hashimoto, Keiji Yada, Ai Yamakage +2
We study bulk electronic states of superconducting topological insulator, which is the promising candidate for topological superconductor. Recent experiments suggest that the three…
Majorana Braiding Dynamics on Nanowires
Cássio Sozinho Amorim, Kazuto Ebihara, Ai Yamakage +2
Superconductors hosting long-sought excitations called Majorana fermions may be ultimately used as qubits of fault-tolerant topological quantum computers. A crucial challenge towar…
Finite-size-effect-induced topological phase transition in a topological crystalline insulator
Hideyuki Ozawa, Ai Yamakage, Masatoshi Sato +1
We study electronic states and topological invariants of (001)-films of topological crystalline insulator (TCI) Pb_{x}Sn_{1-x}Te. Gapless surface Dirac cones on bulk TCIs become ga…
Quantum thermal Hall effect of Majorana fermions on the surface of superconducting topoloigcal insulators
Yosuke Shimizu, Ai Yamakage, Kentaro Nomura
We study the quantum anomalous thermal Hall effect in a topological superconductor which possesses an integer bulk topological number, and supports Majorana excitations on the surf…
Quasi-classical theory of tunneling spectroscopy in superconducting topological insulator
Shota Takami, Keiji Yada, Ai Yamakage +2
We develop a theory of tunneling spectroscopy in superconducting topological insulator (STI), i.e. superconducting state of a carrier-doped topological insulator. Based on the quas…
