[Wien] Charged cells using hybrid functionals

[Marcelo Barbosa]

Dear Gavin,

Thank you very much for your answer.

Since hybrid functional calculations for charged cells is still not possible, do you think that a plausible approach to compare the EFG of different charged states using hybrid functionals could be done by calculating the variation in each EFG orbital component from PBE to hybrid and then consider that a similar variation in each component could be expected for the charged state, therefore enabling an estimation of the EFG for the charged state?

Best regards,
Marcelo

So yes, it seems that hybrid functional calculations for charged cells is still not possible.
