Dear Liang Xiongyi,
- Spin-polarized case is not implemented in turbo_lanczos.x and turbo_davidson.x.
- If your system is metallic (no gap), this is also cannot be studied with the aforementioned codes.
> What should I do?
The only solution I see is to implement what is needed.

Dear QE users,
Now, I use turbo_lanczos.x to calculate the absorption coefficient.
However, I found that Only non-polarized systems are allowed.
My system has odd electron, so I can not use non-polarized calculation (nspin = 1, occupations = fixed )
What should I do? And How can I get absorption coefficient of the system with odd electron ???
