DFT+U

Post by lakhal » Sun Sep 24, 2017 11:24 pm

Dear abinit users
I have a question about DFT + U, I read in the abinit tutorial just the example of LDA + U, my question is: can I use GGA + U or not?
Thanks to all

Hello,

Yes, you can use whatever functional in combination with +U.
Indeed LDA+U should be replaced in general by DFT+U
