Are you using QE v.6.2? in all previous versions, noncollinear EXX doesn't work properly Paolo On Sat, Nov 4, 2017 at 1:07 PM, Debdipto Acharya wrote: > Dear QE users and developers, > > I am currently doing a scf of CsPbI3 cubic unit cell consists of 5 atoms > using noncollinear hybrid functio

[Pw_forum] ERROR dexx is negative in noncollinear hybrid functional calculation

2017-11-06 Thread Debdipto Acharya
Dear QE users and developers, I am currently doing a scf of CsPbI3 cubic unit cell consists of 5 atoms using noncollinear hybrid functional. I have read that ultrasoft pseudopotentials do not work for noncollinear + hybrid. So I have used norm-conserving pseudopotential. I have used 8x8x8 k-point.
