Abstract

We consider the ground state properties, the valence fluctuations and the electronic spectrum in n-doped SmB₆. The behaviour of excess conduction electrons in the presence of valence fluctuations and the origin of the two energy scales in the excitation spectrum are discussed in terms of self-trapped electron-polaron complexes.
