The full-potential all-electron linearized augmented plane wave plus local orbital method, as implemented in the suite of the software wien2k, has been used to systematically investigate …
The high temperature face-centered-cubic delta phase of plutonium (FCC δ-Pu) is metallurgically important in industrial applications and can be stabilized at room temperature …
We detail the creation of a multicenter density functional tight binding (DFTB) model for hydrogen on δ-plutonium, using a framework of new Slater-Koster interaction parameters …

All-electron density functional theory was used to investigate δ-plutonium (δ-Pu) alloyed with gallium (Ga) impurities at 3.125, 6.25, 9.375 atomic (at)% Ga concentrations. The results …
We report on calculations of total and partial densities of states of atoms constituting the high- temperature (HT) tetragonal Tl 3 PbBr 5 phase (space group P4 1) using the full potential …
