Flat Chern bands and correlated states in a spiral magnet
A theoretical study describes how a magnet with spiral order can generate flat Chern bands, that is, electronic bands with nearly constant Berry curvature and minimal dispersion. In this regime, the kinetic energy of the electrons is quenched and Coulomb interactions dominate the physics of the system, opening the door to correlated states with topological properties.
