Anomalous Local Fermi Liquid in -Singlet Configuration: Impurity Model for Heavy-Electron System UPt_3
Satoshi Yotsuhashi, Hiroaki Kusunose, Kazumasa Miyake
It is shown by the Wilson numerical renormalization group method that a strongly correlated impurity with a crystalline-electric-field singlet ground state in the f^2-configuration…
Quasiparticle Interactions for f-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-based heavy fermions, is studied by the Wilson numerical renormalization group me…
Numerical renormalization group study of two-level Kondo effect: Discovery of new fixed point
M. Kojima, S. Yotsuhashi, K. Miyake
The model of two-level Kondo effect is studied by the Wilson numerical renormalization group method. It is shown that there exist a new type of weak-coupling fixed point other than…
Non-Fermi Liquid Behavior of U-impurity with -Singlet Ground State
Satoshi Yotsuhashi, Kazumasa Miyake, Hiroaki Kusunose
It is shown by the Wilson's numerical renormalization-group approach that Non-Fermi liquid (NFL) behaviors arise even for U-impurity with an -singlet ground state, and all the…
Formation of heavy quasiparticle state in two-band Hubbard model
H. Kusunose, S. Yotsuhashi, K. Miyake
A realization of heavy fermion state is investigated on the basis of two-band Hubbard model. By means of the slave-boson mean-field approximation, it is shown that for the intermed…
