spin index for Kohn-Sham Hamiltonian |

- Dear Prof. Ozaki,
I have difficulties in understanding the spin index stored in HS.out for non-collinear magnetic calculations. There are Hamiltonian matrix elements for four spin indexes, i.e., 0, 1, 2, 3. From analysis_example.c, I understand that spin=0 is for spin up while spin=1 is for spin down. I thought that spin=2 and spin=3 are for the couplings between spin up and spin down. So, the matrix elements for spin=2 should be the Hermitian conjugate of those for spin=3. However, it is not what I expected when I take a look at the matrix elements. Could you please explain it? Besides, I want to use the Kohn-Sham Hamiltonian to reproduce the band structure for non-collinear magnetic calculations. Any suggestion will be appreciated.
Best regards,
M. Chen
