Optical and magnetic excitations in the underscreened quasiquartet Kondo lattice
The underscreened Kondo lattice consisting of a single twofold degenerate conduction band and a crystalline electric-field (CEF) split 4f-electron quasiquartet has nonconventional quasiparticle dispersions obtained from the constrained mean-field theory. An additional genuinely heavy band is found i...
