Many-Body Resonance in a Correlated Topological Kagome Antiferromagnet
Many-Body Resonance in a Correlated Topological Kagome Antiferromagnet
We use scanning tunneling microscopy to elucidate the atomically resolved electronic structure in the strongly correlated kagome Weyl antiferromagnet ${\mathrm{Mn}}_{3}\mathrm{Sn}$. In stark contrast to its broad single-particle electronic structure, we observe a pronounced resonance with a Fano line shape at the Fermi level resembling the many-body Kondo resonance. We find …
