Band structure along symmetry lines using HSE functional

Post by anhhv » Thu Feb 28, 2019 3:15 pm

Dear ABINIT developers,

I wonder that the computation for band structures along symmetry lines using HSE is available now? Thank you so much.

Best regards,

Dear Viet-Ahn,

Unfortunately, the computation for band structure with hybrid functionals is not yet implemented in ABINIT.

Best Regards

Dear ABINIT Developers and Users,

I also want to calculate the band structure with HSE functional.

In other topic Marc Torrent posted that the computation of band structure is possible when each k-point will be calculated separately. (see this topic)

Dear Hazem,

For the time being, it is not possible to restart a non-self-consistent calculation with Hybrid functional (Fock) from a density file. It make sense because Fock operator depends directly on the WF.
In a future realease of Abinit, it will (for sure) be possible to restart from the WF.
Meanwhile, to plot a band structure, your only possibility it to compute manually each k-point (have a whole set of key-points containing the ones you want to plot).

How to do this correctly?

I have another question on HSE functional. It is possible to change the value of the omega parameter?
