The XTermKind function

Concerns issues with computing quasiparticle corrections to the DFT eigenvalues - i.e., the self-energy within the GW approximation (-g n), or considering the Hartree-Fock exchange only (-x)

The XTermKind function

Post by sdwang » Sun May 13, 2018 11:39 am

Dear all,
I noticed there is a option in the input file 'XTermKind' for the response calculation. Does it work as 'GTermKind' now?

Thanks!

Dear Shudong,
the terminators' technique for accelerating convergence on empty bands are both implemented for the response function X (XTermKind) and GW summation (GTermKind).
In order to activate them, it is needed to add verbosity in the generation of the input file.

Code: Select all

 "-V resp"
for XTermKind

Code: Select all

"-V qp"
for GTermKind

As usual, using

Code: Select all

"-V all"
you have all the auxiliary variables not set by default.

Best,
Daniele
