query about potential mixing

Dear all,

What is potential mixing?
If for example we take GGA [for our calculations in input file] does the potential remains same in character like GGA [or total potential] or evolve into something else after potential mixing.
Does 'potential mixing' happen in DFPT based calculations.

Thanks in advance.

regards
