A review of the basic ideas and techniques of the spectral density-functional theory is
presented. This method is currently used for electronic structure calculations of strongly …

The experimental technique of angle-and spin-resolved ultraviolet photoemission has been
developed into an important tool for investigating the electronic structure of crystalline …

The relaxation processes of electrons and spins systems following the absorption of
femtosecond optical pulses in ferromagnetic nickel have been studied using optical and …

We discuss a general approach to a realistic theory of the electronic structure in materials
containing correlated d or f electrons. The main feature of this approach is the taking into …

We present an experimental manifestation of how the single-particle density of states around
the Fermi level (EF) changes near a Mott transition. In a metallic perovskite-type 3 d 1 Mott …

Photoemission experiments on 3 d transition metals are reviewed. The emphasis is on
understanding the results of experiments, not on experimental details and methods …

A novel approach to the investigation of correlation effects in the electronic structure of
magnetic crystals which takes into account a frequency dependence of the self-energy (the …

In the framework of LDA+ DMFT (dynamical mean field theory) approach for realistic
electronic structure calculations, a new perturbation scheme which combines the T-matrix …

For narrow electronic bands in metals, we seek improvement over the local-density
approximation (LDA) by including the on-site Coulomb interaction between localized …

Publisher Summary Stimulated by technological prospects of high-density magneto-optical
(MO) recording and by fundamental research on magnetism, a wealth of experimental data …
