Quasiparticle Interactions for f${}^2$-Impurity Anderson Model with Crystalline-Electric-Field: Numerical Renormalization Group Study

Kazumasa Hattori, Satoshi Yotsuhashi, Kazumasa Miyake

The aspect of the quasiparticle interaction of a local Fermi liquid, the impurity version of f${}^2$-based heavy fermions, is studied by the Wilson numerical renormalization group me…
