[Mostafa Youssef]

Dear Subhodip,

Check example04 provided with pw.x. You can find it  in:

/Espresso_folder/PW/examples/example04



>From README:
example04:
    This example shows how to calculate the polarization via Berry
    Phase in PBTiO3 (contributed by the Vanderbilt Group in Rutgers
    University).

I would also recommend this paper:
