Electronic Properties of Transuranium Compounds with HoCoGa-Type Tetragonal Crystal Structure
Takahiro Maehira, Takashi Hotta, Kazuo Ueda +1
By using a relativistic linear augmented-plane-wave method with the one-electron potential in the local-density approximation, we investigate energy band structures and the Fermi s…
Theory of Fano-Kondo effect of transport properties through quantum dots
Isao Maruyama, Naokazu Shibata, Kazuo Ueda
The Fano-Kondo effect in zero-bias conductance is investigated based on a theoretical model for the T-shaped quantum dot. The conductance as a function of the gate voltage is gener…
Kondo hole in one-dimensional Kondo insulators
Isao Maruyama, Naokazu Shibata, Kazuo Ueda
Properties of a nonmagnetic impurity in Kondo insulators are investigated by considering a one-dimensional Kondo lattice model with depletion of a localized spin. The ground-state…
Conductance through Quantum Dots Studied by Finite Temperature DMRG
Isao Maruyama, Naokazu Shibata, Kazuo Ueda
With the Finite temperature Density Matrix Renormalization Group method (FT-DMRG), we depeloped a method to calculate thermo-dynamical quantities and the conductance of a quantum d…
Theory of Metal-Insulator Transition in PrRu4P12 and PrFe4P12
S. H. Curnoe, H. Harima, K. Takegahara +1
All symmetry allowed couplings between the 4f^2-electron ground state doublet of trivalent praseodymium in PrRu4P12 and PrFe4P12 and displacements of the phosphorus, iron or ruthen…
Odd-Parity Triplet Pair Induced by Hund's Rule Coupling
Takashi Hotta, Kazuo Ueda
We discuss microscopic aspects of odd-parity triplet pair in orbital degenerate systems. From the concept of off-diagonal long-range order, a pair state is unambiguously defined as…
