Re: Non Linear calculation input for ferromagnetic system

Dear Andy,

I'm sorry to confirm that there is a problem with the code for a ferromagnetic system. Thank you for bringing it up.

This issue is taken into account now, and I will let you know when the correction will be done.

Regards,
Lucas

Re: DFPT phonon with soc problem:rhoijim must be allocated!

Dear Andy,

What I can say for sure is that the nonlinear implementation works for nspinor=1 and nsppol=1 or 2.

For now Abinit doesn't provide tools to compute Raman intensities without using DFPT...

Best wishes,

Re: DFPT phonon with soc problem:rhoijim must be allocated!

Dear Andy, The error you see says that in the case of non-linear computations (optdriver=5) with the "FULL DFPT" method (usepead=0) the variable "occopt" should be 1 (0 should be fine too, I think). Indeed this routine has been validated only in the case of insulators. It's true that in principle on...

Re: DFPT

Dear wlsong, I am not an expert on Berry phase computations, but I used it a little some years ago. 1) Have you tried kptopt = 3 (instead of 2) ? By the way, I see in your input file that ngkpt = 13 13 1 , is the use of one kpoint in the third axis intended? 2) You can use an other implementation of...
