Antiferro-quadrupole state of orbital-degenerate Kondo lattice model with f^2 configuration
Hiroaki Onishi, Takashi Hotta
To clarify a key role of orbitals in the emergence of antiferro-quadrupole structure in PrPb, we investigate the ground-state property of an orbital-degenerate Kondo latt…

Multipole State of Heavy Lanthanide Filled Skutterudites
Takashi Hotta
We discuss multipole properties of filled skutterudites containing heavy lanthanide Ln from a microscopic viewpoint on the basis of a seven-orbital Anderson model. For Ln=Gd, in co…

Enhanced Kondo Effect in an Electron System Dynamically Coupled with Local Optical Phonon
Takashi Hotta
We discuss Kondo behavior of a conduction electron system coupled with local optical phonon by analyzing the Anderson-Holstein model with the use of a numerical renormalization gro…
