LIBXC1 = [integer] or [string]

Description: LIBXC1 and LIBXC2 specify the functionals from the library of exchange-correlation functionals ^[1]^[2] that one wants to use.

LIBXC1 and LIBXC2 can be either integers or strings. The available functionals are listed on the Libxc website^[3] and are essentially of three types: exchange (_X_), correlation (_C_) or exchange-correlation (_XC_). The possibilities for LIBXC1 and LIBXC2 are the following:

Both LIBXC1 and LIBXC2 are used and correspond to the exchange (_X_) and correlation (_C_) functionals, respectively, or the reverse.
Only LIBXC1 (or LIBXC2 ) is used and corresponds to an exchange (_X_) or exchange-correlation (_XC_) functional. It can also be a correlation (_C_) functional, but such a calculation without exchange would not make sense.
