SmO thin films: a flexible route to correlated flat bands with nontrivial topology
Using density functional theory based calculations, we show that the correlated mixed-valent compound SmO is a three-dimensional strongly topological semimetal as a result of a 4f−5d band inversion at the X point. The [001] surface Bloch spectral density reveals two weakly interacting Dirac cones th...
