Engineer magnetic bi-layer honeycomb with photon-phonon interaction.
ORAL
Abstract
Phonon-photon interaction could be used to engineer magnetic system. A bilayer honeycomb lattice model is discussed. Phonon-photon interaction is utilized here to generate interlayer DM interaction which leads to a non-collinear spin groundstate and a topological phase transition. We did a group thoery analysis on the phonon modes and spectrum calculations on magnon in the system. A transition from gapped magnon phase to topological magnon nodal line phase is analyzed.
