I'm currently looking at the following set of notes and am confused at equation (1.15) where they discuss the Bogoliubov quasiparticle for the edge states. I understand up to equation (1.14), where they have solved for the edge state of the first-quantized Hamiltonian. What I don't understand is how they derived the field operator in (1.15).
