    • Here we still use the DFT-LDA single-particle wave functions because they usually almost overlap with the quasiparticle wave functions; see, for example, Ref. [19].

    • note
    • The small damping broadens the line shape of coupling but has no effect to the occupation probability because of the frequency integral in Eq. (4).
