Mulliken population analysis for excited state

[Simil Thomas]

Dear all,

Would it be possible to get excited state Mulliken population analysis in cp2k?

I could print it for my ground state and excited state jobs while Mulliken population is found to be nearly same for ground and excited state (where I was expecting a charge transfer looking at valence band and conduction band pdos; valence band is localized on one fragment and conduction band on another fragment in a Metal–organic frameworks).

The keyword I used is

&FORCE_EVAL

.........

      &PRINT

        &MULLIKEN
          &EACH
           GEO_OPT 1
          &END EACH
        &END MULLIKEN

      &END PRINT

with regards

Simil

Hi

there is no obvious/unique definition what a Mulliken population analysis for TDDFT would be.
The PRINT segment you are using is only active for the ground state density matrix.
For an analysis of the excitation I would suggest to use the Orbital coefficients printed or NTOs.

regards
JH
