Solids exhibit a variety of electronic properties such as elastic, magnetic, thermodynamic,
transport properties, etc. Above all, the difference between insulating and metallic properties …

We found direct experimental evidence for an orbital switching in the V 3 d states across the
metal-insulator transition in VO 2. We have used soft-x-ray absorption spectroscopy at the …

We present a detailed study of the valence and conduction bands of VO 2 across the metal-
insulator transition using bulk-sensitive photoelectron and OK x-ray absorption …

By the local density approximation with on-site Coulomb repulsion U (LDA+ U) method with
spin-orbit coupling (LDA+ U+ SO) the magnetic state and electronic structure have been …

accepted February 20, 2006; published May 10, 2006) Theoretical studies on charge
ordering phenomena in quarter-filled molecular (organic) conductors are reviewed …

Recent developments in research into superconductivity in organic materials are reviewed.
In the epoch-defining quasi-one-dimensional TMTSF superconductors with T c∼ 1 K, T c …

We study thermoelectric effects in a Kondo correlated quantum dot coupled to ferromagnetic
electrodes by calculating conductance, thermopower, and thermal conductance in the …

We present neutron scattering spectra taken from a single crystal of Na 0.75 CoO 2, the
precursor<? format?> to a novel cobalt-oxide superconductor. The data contain a prominent …

We systematically investigate electron transport through double quantum dots with particular
emphasis on interference induced via multiple paths of electron propagation. By means of …

Spin and charge fluctuations and superconductivity in Na x CoO 2· y H 2 O are studied
based on a multiorbital Hubbard model. Tight-binding parameters are determined to …
