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…
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…
Magnetic Response of Majorana Kramers Pairs Protected by Z2 Invariants
Yuki Yamazaki, Shingo Kobayashi, Ai Yamakage
On the surface of time-reversal-invariant topological superconductors, Kramers pairs of Majorana fermions with chiral and crystalline symmetries exhibit completely uniaxial or octu…
