Renormalization of Coulomb interactions in s-wave superconductor Na$_x$CoO$_2$

, 2006
We study the renormalized Coulomb interactions due to retardation effect in Na$_x$CoO$_2$. Although the Morel-Anderson's pseudo potential for $a_{1g}$ orbital $\mu^*_{a1g}$ is relatively large because the direct Coulomb repulsion $U$ is large, that for ...

Theoretical Analysis of the Reduction of Neel Temperature in La$_{2}$(Cu$_{1-x}$Zn(or Mg)$_x)$O$_{4}$

, 2006
Using Tyablikov's decoupling approximation, we calculate the initial suppression rate of the Neel temperature, $R_{IS}=-lim_{x-> 0} T^{-1}_{N} dT_{N}/dx$, in a quasi two-dimensional diluted Heisenberg antiferromagnet with nonmagnetic impurities of ...

Effect of Hund's rule coupling on SU(4) spin-orbital system

, 2006
We investigate the ground-state property of a one-dimensional two-orbital Hubbard model at quarter filling by numerical techniques such as the density-matrix renormalization group method and the exact diagonalization. When the Hund's rule coupling $J$ is

The de Haas-van Alphen effect in Kondo systems with crystalline electric field

, 2006
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 mass enhancement per Ce ion in the periodic system is identical with that ...

Enhanced low-temperature entropy and flat-band ferromagnetism in the t-J model on the sawtooth lattice

, 2007
Using the example of the sawtooth chain, we argue that the t-J model shares important features with the Hubbard model on highly frustrated lattices. The lowest single-fermion band is completely flat (for a specific choice of the hopping parameters $t_{i ...

Nonlocal spin Hall effect and spin-orbit interaction in nonmagnetic metals

, 2006
Spin Hall effect in a nonlocal spin-injection device is theoretically studied. Using a nonlocal spin-injection technique, a pure spin current is created in a nonmagnetic metal (N).
