Nonlinear spin-wave theory with self-energy corrections and two-magnon bound-state resummation quantitatively matches CrBr3 magnon data up to Tc and finds thermally reduced but stable gaps in gapped Dirac materials like CrI3, with a ~5% DMI/exchange ratio criterion for observability.

Light-matter coupling expansion of the magnon Hamiltonian yields the Fleury-Loudon Raman vertex, directly connecting Raman circular dichroism to magnon band Berry curvature.
First-principles calculations show robust charge properties but tunable spin Berry curvature, spin Hall conductivity, and magnon excitations in strained CrSiSe3 monolayer under electric fields up to 0.3 V/Å.
