Deskripsi
The interaction between antiferromagnetic magnons and electrons sits at the heart of many strongly correlated systems, however, investigation has been hampered by a lack of clear-cut examples. Here, Yu et al directly observe a kink in the dispersion, a result of renormalization due to the electron-antiferromagnetic magnon interaction.
