The de Haas-van Alphen effect in Kondo systems with crystalline electric field
J. Otsuki, H. Kusunose, Y. Kuramoto
The effective mass probed by the de Haas-van Alphen oscillations is studied for a model Ce system under magnetic field higher than the Kondo energy. In the mean-field theory, the m…
Self-Consistent Perturbation Theory for Thermodynamics of Magnetic Impurity Systems
J. Otsuki, H. Kusunose, Y. Kuramoto
Integral equations for thermodynamic quantities are derived in the framework of the non-crossing approximation (NCA). Entropy and specific heat of 4f contribution are calculated wi…
Electron Addition Spectrum in the Supersymmetric t-J Model with Inverse-Square Interaction
Mitsuhiro Arikawa, Yasuhiro Saiga, Yoshio Kuramoto
The electron addition spectrum A^+(k,omega) is obtained analytically for the one-dimensional (1D) supersymmetric t-J model with 1/r^2 interaction. The result is obtained first for…
Exact dynamical structure factor of the degenerate Haldane-Shastry model
Takashi Yamamoto, Yasuhiro Saiga, Mitsuhiro Arikawa +1
The dynamical structure factor of the K-component (K = 2,3,4) spin chain with the 1/r^2 exchange is derived exactly at zero temperature for arbitrary size of the system. T…
Orbital Kondo Effect in CeLaB: Scaling Analysis
H. Kusunose, Y. Kuramoto
Peculiarity of the Kondo effect in CeLaB is investigated on the basis of the scaling equations up to third order. For the case where the - charge fluctuat…
