Dear PWSCF users:
In Phys.Rev.Lett., Prof. Mauri proposed a method
to calculated Raman intensities quickly, which was said
have been implemented in the PWSCF code. How can I perform
such calculations with PWSCF?
It's said that the PWSCF can determine the Hubbard U
parameter in LDA+U calculations automaticaly. But in the
INPUT.PW I also find that I need to give Hubbard_U as a
parameter, why?
Thanks.
