$LIBXC group          (relevant for DFTTYP=USELIBXC)
 
    This group controls some variables while LibXC will be
called. The behavior when one of the next parameters is set
(CHF, CMP2, LC, MU, LRDFLG, LAMBDA, KAPPA or RZERO) from
DFT group is not defined. Please, avoid to use it with
DFTTYP=USELIBXC.
 
    It is dangerous to mix FMO code with LibXC interface
since some DFT variables are overridden in FMO code. So if you
want to use functionals from LibXC, please check your results
carefully!
 
    Due to this group uses a non-standard input file reader,
the interface between LibXC and GAMESS can be compiled using
with the following compilers: GCC (since 5.0.0),
                              Intel (tested since 15.0), and
                              PGI (tested since 19.10).
The correct compilation is not guaranteed with lower versions
or with other compilers.
 
    If you want to use another compiler, which is not in this
list, please, verify that it supports the new Fortran 2008
allocate statement abilities (SOURCE=).
 
    WARNING:
    - With PGI, Float-Point Exceptions are possible, so this
      compiler is not recommended
    - This GAMESS extension is not supported by the following
      compilers and their versions:
      1) IBM XLF (all version)
      2) GCC (before 5.0.0, e.g. 4.9.4)
 
    In citation, we recommend to specify used LibXC version.

    HFEX       = a ratio of exact exchange. By default, it
                     is set to zero.
    MP2        = a ration of non-local MP2 correlation for
                     both types of spins. By default, it
                     is set to zero.
    MP2SS      = a ratio of non-local same-spin MP2
                     correlation. By default, it is set to
                     zero. If it set and MP2 also set the
                     MP2 will not be rewritten and it can
                     lead to strange behavior.
    MP2OS      = a ratio of non-local opposite-spin MP2
                     correlation. By default, it is set to
                     zero. If it set and MP2 also set the
                     MP2 will not be rewritten and it can
                     lead to strange behavior.
                 If MP2SS and MP2OPP are equals, then
                     default MP2 will be calculated. In the
                     other case, SCS-MP2 will be used,
                     which does not allow to perform UHF
                     calculation.
    FUNCTIONAL = a name of chosen functional. By default,
                     it is set to a blank line. If the
                     FUNCTIONAL keyword is not presented or
                     FUNCTIONAL=MIXED, the functional will
                     be constructed from groups related to
                     $LIBXC. Below the list of all possible
                     value is presented. In almost all
                     cases, the citation of those
                     functionals will be presented in the
                     LOG file, but we recommended to check

user-defined functionals:
               Functional keyword is not presented
               = MIXED
    In this case, functionals can be constructed from other functionals.
For example, a functional with 30% of Hartree-Fock with 50% of PBE exchange
and 20% TPSS exchange with 100% of TPSS correlation is obtained with the
following input:
 $LIBXC FUNCTIONAL=MIXED HFEX=0.3 $END
 $GGA_X  PBE=0.5  $END
 $MGGA_X TPSS=0.2 $END
 $MGGA_C TPSS=1.0 $END
 
Similarly, DH-DFT can be set. For example, PBE0-DH functional:
 $LIBXC FUNCTIONAL=MIXED HFEX=0.5 MP2=0.128 $END
 $GGA_X  PBE=0.5     $END
 $GGA_C  PBE=0.0.872 $END
 
For using functionals from Hybrid groups (HLDA, HGGA, HMGGA),
full part of HYBRID DFT functional is required. For example, the setting
of PBE0 (also known as PBE1PBE) is the following:
 $LIBXC FUNCTIONAL=MIXED HFEX=0.25 $END
 $HGGA_XC PBEH=1.0 $END
 
Note, that functionals, provided by MIXED, extract only
exchange-correlation parts of functionals without any corrections,
like CAM, LC, or dispersion corrections.
