Odd-frequency pair in topological superconductivity of 1D magnetic chain
Hiromi Ebisu, Keiji Yada, Hideaki Kasai +1
A chain of magnetic atoms with non-collinear spin configuration on a superconductor is a promising new system that can host Majorana Fermions (MFs). In this study, we clarify that…
Anomalous surface states at interfaces in p-wave superconductors
S. V. Bakurskiy, A. A. Golubov, M. Yu. Kupriyanov +2
We present the results of theoretical study of surface state properties in a two-dimensional model for triplet -wave superconductors. We derive boundary conditions for Eilenberg…
Crossed surface flat bands of Weyl semimetal superconductors
Bo Lu, Keiji Yada, Masatoshi Sato +1
It has been noted that certain surfaces of Weyl semimetals have bound states forming open Fermi arcs, which are never seen in typical metallic states. We show that the Fermi arcs e…
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 edge states and topological properties in 1D/2D Rashba semiconductor proximity coupled to iron-based superconductor
Hiromi Ebisu, Keiji Yada, Hideaki Kasai +1
We study Majorana edge states and their topological properties of one-dimensional(1D) and two-dimensional(2D) Rashba semiconductor deposited on iron-based superconductor under the…
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…
