Description
Rev. B 104, 075152 (2021) We studied antiferromagnetic magnons in one-, two- and three-orbital Hubbard model of square and bcc cubic lattice at intermediate coupling using dynamical mean-field theory (DMFT).
We investigate the effect of anisotropy introduced by an external magnetic field or single-ion anisotropy. For the latter we tune continuously between the easy-axis and easy-plane models. We also analyze a model with spin-orbit coupling in cubic site-symmetry setting.

The ordered states as well as the magnetic excitations are sensitive to even a small breaking of SU(2) symmetry of the model and follow the expectations of spin-wave theory as well as general symmetry considerations. magnon.zip: Manuscript files for submission text +figs. magnon_data.tgz: Final and intermediate data. Detailed description of scripts and codes including versions (available on github) in README.md collective...ipynb: python notebook to generate figures in the text, includes selection of k-paths, definition of colorscales, etc.
