Critical Nature of Non-Fermi Liquid in Spin 3/2 Multipolar Kondo Model
Kazumasa Hattori
A multipolar Kondo model of an impurity spin S_I=3/2 interacting with conduction electrons with spin s_c=3/2 is investigated using boundary conformal field theory. A two-channel Ko…
Realization of Heavy Local Fermi Liquid and Non-Fermi Liquid in f Crystalline-Electric-Field Singlet-Triplet Configuration
Kazumasa Hattori, Kazumasa Miyake
Using the numerical renormalization group method, we investigate an extended Anderson model, in which correlated electrons with the (singlet)-(triplet) f crystall…
Local Heavy Quasiparticle in Four-Level Kondo Model
Kazumasa Hattori, Yosuke Hirayama, Kazumasa Miyake
An impurity four-level Kondo model, in which an ion is tunneling among 4-stable points and interacting with surrounding conduction electrons, is investigated using both perturbativ…
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…
