Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The calculated equations of state of the transition metals are dominated by the d-electron contribution to bonding and at the end of the 3d series the metals become magnetic. In contrast, the calculated equations of state of the rare earths are characteri

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We report ab initio calculations of the ground state and optical properties of CeN, which show that the 4f electrons in CeN are itinerant and that the intra-atomic 4f-Coulomb interaction is largely screened. A coherent 4f band of width similar to 2 eV is
