Dear All,
I wanted to check initial state core levels in hybrid calculations and compare them with the results from GGA calculations, however I found there was some wrong in hybrid calculations.
For example, the core level of O1s is usually around -500 eV from GGA calculation, while it is just around -70 eV in hybrid calculation.
Is it a bug in HSE06 or core level routine?

core level from HSE06 and DFT+U
core level shifts are not implemented for the hybrid functionals (so far)

Re: core level from HSE06 and DFT+U
I'm following up this old poster and to check whether core level shift calculation has been implemented for the hybrid functional. I ask it because one paper (http://dx.doi.org/10.1063/1.4889919) has reported core level shifts calculated using vasp-PBE0. Also, the authors shown hybrid PBE0 can improve core level shifts in comparison with PBE. Thanks!

The implementation of the core-level shift code was not extended to hybrid functionals.
Contact the authors of the paper if their code is available for other researchers.
