Research interests:

Topology and transport of bosonic quasiparticles (magnons and phonons) in magnetic insulators.

Using microscopic models and symmetry principles, I study the emergent properties of collective excitations in complex magnetic phases—including noncollinear antiferromagnets, Kitaev magnets, altermagnets, and odd-parity-wave magnets. My primary goal is to bridge microscopic theory and macroscopic observables to identify unique, experimentally accessible signatures.

Key areas of investigation include:

  • Topological Magnonics: Developing novel detection methods for topological magnons.
  • Magnon-Phonon Interactions: Understanding how hybridization impacts the thermal Hall effect and phonon angular momentum.
  • Spin Transport: Investigating the fundamental nature of magnon spin and its associated transport properties.
