Deconstruction of the Kondo Effect near the AFM-Quantum Critical Point
H. Maebashi, K. Miyake, C. M. Varma
The problem of a spin-1/2 magnetic impurity near an antiferromagnetic transition of the host lattice is solved. The problem is shown to transform to a multichannel problem. A varie…
Anomalous Magnetism of UPT_{3}:
Yukihiro Okuno, Kazumasa Miyake
UPt exhibits a paradoxical behavior in its antiferromagnetism. Namely, the neutron scattering experiments surely detect the antifferomagnetic ordering below the transition…
Impurity Effects in Strongly Correlated Metals: Large Pressure Dependence of Residual Resistivity of Heavy Fermions
Hiroaki Ikeda, Kazumasa Miyake
It is shown on the basis of the Fermi liquid theory that the s-wave scattering potential due to nonmagnetic impurity is strongly enhanced by the mass enhancement factor . As a…
Aspect of Spin-Charge Separation due to Antiferromagentic Spin Fluctuations in Technically Nested 2D Metals
Kazumasa Miyake, Osamu Narikiyo
It is shown that the charge susceptibility in nearly half-filled two-dimensional (2D) metals, with technically nested Fermi surface, shows anomaly at the wavevector different from…

Kazumasa Miyake, Osamu Narikiyo
Comment on `Anomalously Large Gap Anisotropy in the a-b Plane of BiSrCaCuO', Kazumasa Miyake and Osamu Narikiyo, In a recent Letter, She…
