[Pw_forum] "DFT+U"

[francesca costanzo]

Dear all,
I have a question concerning DFT+U approach in PW,
according to the linear response theory (Ref. PRB, 67, 153106, 2003).
I would like to set in my input for the b-NiOOH structure,
the value of U-J effective of 5.5 for Ni.

If I understand well, I should set in the
&system section
the lda_plus_u = .true.,
 U_projection_type = 'atomic',

and how I can set U-J effective=5.5 eV?

I got confused from all the keywords in the input file descriptions.

thank you in advance for your help.

                                         Francesca
