[CP2K-user] [CP2K:17486] Re: How to add MOS independently for spin up and spin down

[Jürg Hutter]

ADDED_MOS {Integer} ...
Number of additional MOS added for each spin. Use -1 to add all available. alpha/beta spin can be specified independently (if spin-polarized calculation requested).
This keyword cannot be repeated and it expects a list of integers.
Default value: 0

For UKS calculations this means for example

ADDED_MOS    10    11

or to make it simple use -1 to get all states.

regards

JH

Hi,

I was wondering anyone have experienced this issue? If the numbers of orbitals of spin-up and spin-down are different, then g-tensor calculation would be terminated.. So adding MOS independently for spin-up and spin-down would be necessary.

Thanks,
Hongyang

Hi,

I'm a newbie using cp2k/9.1.0.<http://9.1.0.> I tried to use LSD and ADDED_MOS to add the MOS independenly for spin up and spin down. But based on the output file, it seems 9 MOS are added both in spin up and spin down rather than 9 MOS for spin up and 10 for spin down as what I set in the input file. I'm wondering did I make any mistake in the input file? How could I add different number of MOS on spin up and down states?

Best,
Hongyang
