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…

Generalized Berry phase for a bosonic Bogoliubov system with exceptional points
Terumichi Ohashi, Shingo Kobayashi, Yuki Kawaguchi
We discuss the topology of Bogoliubov excitation bands from a Bose-Einstein condensate in an optical lattice. Since the Bogoliubov equation for a bosonic system is non-Hermitian, c…
