Nonlinear magnon spin Nernst effect in antiferromagnets and strain-tunable pure spin current

Hiroki Kondo, Yutaka Akagi

In this Letter, we study the spin Nernst effect (SNE) of magnons in the nonlinear response regime. We derive the formula for the nonlinear magnon spin Nernst current by solving the…

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…

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…

Three-dimensional topological magnon systems

Hiroki Kondo, Yutaka Akagi, Hosho Katsura

We propose a class of models for a magnonic analog of topological insulators in three dimensions. The models have pseudo-time-reversal symmetry which ensures the existence of boson…

Topological Invariant for Magnon Spin Hall Systems

Hiroki Kondo, Yutaka Akagi, Hosho Katsura

We propose a definition of a topological invariant for magnon spin Hall systems which are the bosonic analog of two-dimensional topological insulators in class AII.…
