Density Functional Theory Parameters¶
The reader who wishes to revise the fundamental theoretical framework underlying DFT is referred to the introductory literature on the subject.
We present in what follows the parameters which apply specifically to the DFT model type.
We support the following Subtypes:
We support the following list of exchange-correlation functionals.
NOTE: for planewave pseudopotential DFT the functional part matches that used in the corresponding pseudopotential
The following can be used as example refiners for the DFT model.
DFT calculations might of might not treat the spin-orbit coupling interaction or magnetic interactions, which are both considered modifiers:
- Spin-Orbit Coupling (soc), a relativistic quantum physical interaction of a particle's spin with its motion inside a potential 5.
- Magnetism (magn), resulting from the spontaneous polarization (parallel lining up) of the spins of conduction electrons in ferromagnetic metals, such as iron, nickel and cobalt, giving rise to a magnetic moment in these materials even in the absence of an externally applied magnetic field 6.
Additional resourceful general references on DFT and associated concepts, beyond those outlined below, are contained in this page, to be referred to at the reader's discretion.
