The M06 suite of functionals [13] [14] is a set of four meta-hybrid GGA and meta-GGA DFT functionals. These functionals are constructed by empirically fitting their parameters, while being constrained to a uniform electron gas. The family includes the functionals M06-L, M06, M06-2X and M06-HF, with a different amount of exact exchange for each one.
Like the 12 family, the functionals are based on a non-separable form, but unlike the 11 or 12 families the hybrid functional doesn't use range separation: MN15 is a global hybrid like in the pre-11 families. The 15 family consists of two functionals MN15, [30] a global hybrid with 44% HF exchange. MN15-L, [31] a local functional with 0% HF ...
Local-density approximations are important in the construction of more sophisticated approximations to the exchange-correlation energy, such as generalized gradient approximations (GGA) or hybrid functionals, as a desirable property of any approximate exchange-correlation functional is that it reproduce the exact results of the HEG for non ...
The basic methodology is density functional theory (DFT), but the code also allows use of post-DFT corrections such as hybrid functionals mixing DFT and Hartree–Fock exchange (e.g. HSE, [3] PBE0 [4] or B3LYP [5]), many-body perturbation theory (the GW method [6]) and dynamical electronic correlations within the random phase approximation (RPA ...
This is a list of genetic hybrids which is limited to well documented cases of animals of differing species able to create hybrid offspring which may or may not be infertile. Hybrids should not be confused with genetic chimeras , such as that between sheep and goat known as the geep .
