Quasiparticle on Bogoliubov Fermi Surface and Odd-Frequency Cooper Pair
Dakyeong Kim, Shingo Kobayashi, Yasuhiro Asano
We discuss a close relationship between a quasiparticle on the Bogoliubov Fermi surface and an odd-frequency Cooper pair in a superconductor in which a Cooper pair consisting of tw…
Possible topological phases in quantum anomalous Hall insulator/unconventional superconductor hybrid systems
Ryoi Ohashi, Shingo Kobayashi, Yukio Tanaka
Quantum anomalous Hall insulator (QAH)/-wave superconductor (SC) hybrid systems are known to be an ideal platform for realizing two-dimensional topological superconductors with…
Electric Multipoles of Double Majorana Kramers Pairs
Yuki Yamazaki, Shingo Kobayashi, Ai Yamakage
A single Majorana Kramers pair hosts only one component of the magnetic multipole. This can be used to determine the bulk Cooper-pair symmetry through surface-sensitive spectroscop…
Josephson effect of superconductors with electrons
Dakyeong Kim, Shingo Kobayashi, Yasuhiro Asano
The angular momentum of an electron is characterized well by pseudospin with in the presence of strong spin-orbit interactions. We study theoretically the Josephson effect…
Majorana multipole response: General theory and application to wallpaper groups
Shingo Kobayashi, Yuki Yamazaki, Ai Yamakage +1
Whereas identification of Cooper pair symmetry is the first and crucial step in the investigation of unconventional superconductors, only a few have been established so far because…
Magnetic response of Majorana Kramers pairs with an order-two symmetry
Yuki Yamazaki, Shingo Kobayashi, Ai Yamakage
We study an intrinsic relation between the topology of bulk electronic states and magnetic responses of Majorana Kramers pairs, Kramers pairs of Majorana fermions, on a surface of…
