Confused about Bogoliubov transformation

  1. So I was told by my teacher today that I am doing the bogoliubov transformation wrong because I'm supposed to have 4 different vectors,

    i.e

    Instead of Ak and Bk

    A1k
    A2k

    and
    B1k
    B2k

    I'm wondering how this makes sense. I've seen papers with 2 different vectors and their complex counterparts but never 4 different vectors. Any help would be great.

    Maybe you can give us the expressions you obtained for A and B.
