30. Note that in the same expansion written in Ref. 19 (Eq. (1)) there was a misprint in the sign of the argument of the exponential after g(z).
31. The functions f and g in the notation of standard Bogoliubov theory are called u and v, respectively.

34. Different states at the same energy and wave vector can be found by varying the thickness of the slab and/or the size of the computational box. This procedure is equivalent to solve the equations of motion at fixed energy, slab and box, but different boundary conditions. We work with fixed boundary conditions (f and g vanish at the boundary).
