Greetings,
I understand that the implementation of the TB09 meta gga is done
in Espresso
though Libxc, as described in the article by Germaneau and colleagues.
However, while looking through the code it seems that at no point
the c parameter
(equation 3 of PRL 102, 226401 (2009)) is set with
xc_f90_mgga_x_tb09_set_par thus
leaving c equal to 1 by default (i.e. the original BJ is used).
Could someone please check if this is actually a bug of if c is
actually set?
Best regards,
