BH-DFTB/DFT calculations for iron clusters
AIP Advances, 2016 We present a study on the structural, electronic, and magnetic properties of Fen(n = 2 − 20) clusters by performing density functional tight binding (DFTB) calculations within a basin hopping (BH) global optimization search followed by density ...

A DFT Study of Ruthenium fcc Nano-Dots: Size-Dependent Induced Magnetic Moments
Nanomaterials, 2023 Many areas of electronics, engineering and manufacturing rely on ferromagnetic materials, including iron, nickel and cobalt. Very few other materials have an innate magnetic moment rather than induced magnetic properties, which are more common.

Explicit demonstration of the equivalence between DFT+U and the Hartree-Fock limit of DFT+DMFT
Physical Review ResearchSeveral methods have been developed to improve the predictions of density functional theory (DFT) in the case of strongly correlated electron systems. Out of these approaches, DFT+U, which corresponds to a static treatment of the local interaction, and ...
