Theoretical Background

Meta-GGA exchange-correlation functionals depend on the electron density , its first derivative and the kinetic-energy density :

Although meta-GGAs are slightly more expensive than GGAs, they are still fast to evaluate and appropriate for very large systems. In general, meta-GGA functionals are more accurate than GGAs. Not that meta-GGAs are implemented in VASP within the generalized KS scheme [1] The meta-GGA that is currently widely used in solid-state physics is SCAN[2].

How to

A meta-GGA can be used with the tag METAGGA in the INCAR file.
