Recent results on magnetic and spectroscopic properties of transition metals, alloys and their surfaces, which were obtained by the LSDA+DMFT approach will be reviewed in this article. We exploit the various advantageous features offered by a LSDA+DMFT implementation on the basis of the KKR band structure method. This fully self consistent approach, with respect to charge and self-energy, allow...

We present a technique for enhancing Fermi surface ~FS! signatures in the two-dimensional ~2D! distribution obtained after the 3D momentum density in a crystal is projected along a specific direction in momentum space. These results are useful for investigating fermiology via high-resolution Compton scattering and positron annihilation spectroscopies. We focus on the particular case of the ~110...

The “Standard Model” of the Electronic Structure of Dots Progress made in the growth of “freestanding” (e.g., colloidal) quantum dotslt2 (see also articles in this issue by Nozik and MiCi6, and by Alivisatos) and in the growth of semiconductor-embedded (“self-assembled”) dots3p4 (see also the article by Bimberg, Grundmann, and Ledentsov in this issue) has opened the door to new and exciting spe...

Tat protein, released by HIV-infected cells, has a battery of important biological effects leading to distinct AIDS-associated pathologies. Cell surface heparan sulfate protoglycans (HSPGs) have been accepted as endogenous Tat receptors, and the Tat basic domain has been identified as the heparin binding site. However, findings that deletion or substitution of the basic domain inhibits but does...

Isoelectronic heavy elemental substitutions are generally preferred for enhancing the phonon scattering in a material without deteriorating its electrical transport. In this work, we demonstrate efficacy and contrasting role of bismuth, an isoelectronic substitute antimony, thermoelectric transport structurally ordered cubic VFeSb half-Heusler. Despite limited solubility, Bi-substitution at Sb-...

The antiferromagnetic ordering that MnBi2Te4 shows makes it invariant with respect to the combination of time-reversal and primitive-lattice translation symmetries, giving rise its topologically nontrivial nature a number fundamental phenomena. At same time, possibility control electronic magnetic properties this system can provide new effective ways for application in devices. One approaches m...

Due to its strong magnetocrystalline anisotropy, FePt L1$\mathrm{_0}$ phase is considered as a promising magnetic recording media material. Although the properties of this have already been analyzed many times using density functional theory (DFT), we decided study it again, emphasizing on full potential methods, including spin-polarized relativistic Korringa-Kohn-Rostoker (SPR-KKR) and full-po...
