SOGGA.PBE
« on: December 20, 2019, 14:12 »
Hi,

1) For SOGGA.PBE calculation, I find 'force_ timereversal = False". What does that signify?

2) Besides, the default pseudopotential is set to --> 'SG15-SO [ ] SOGGA.PBE'.  Can't we use 'OMX [ ] GGA.PBE' for SOC calculations?

Thanks and Regards_

Besides, I wanted to know_

Is there any Ref/Tutorial available on 'PlaneWaveCalculator'_QATK2019.12 ?

1) spin-orbit coupling breaks time-reversal symmetry, so k-point reduction from time-reversal must be switched off.
2) looks like with LCAO uou can also use OMX for SOGGA. Not sure if OMX is available for PlaneWave also.

We have no plane-wave tutorial specifically for Q-2019.12 release. But we do have this one: https://docs.quantumatk.com/tutorials/pw_intro/pw_intro.html
