Dirac surface states in magnonic analogs of topological crystalline insulators
Hiroki Kondo, Yutaka Akagi
We propose magnonic analogs of topological crystalline insulators which possess Dirac surface states protected by the combined symmetry of time-reversal and half translation. Const…

Topological Invariant for Bosonic Bogoliubov-de Gennes Systems with Disorder
Yutaka Akagi
Using the method of noncommutative geometry, we define a topological invariant in disordered bosonic Bogoliubov-de Gennes systems, which possess a unique mathematical property---no…

Non-Hermiticity and topological invariants of magnon Bogoliubov-de Gennes systems
Hiroki Kondo, Yutaka Akagi, Hosho Katsura
Since the theoretical prediction and experimental observation of the thermal Hall effect of magnons, a variety of novel phenomena that may occur in magnonic systems have been propo…
