Creation/annihilation operators question

[QUOTE="Antarres, post: 6324161, member: 643619"] Hmm, that is clear. I am actually aware that, if we take a finite volume of direct space, that makes the momentum space discrete. So the solution to this would be to switch to discrete momentum space and then take the thermodynamic limit where volume tends to infinity, which would yield continuum of momentum states? Or, taking this interesting rescaling of creation/annihilation operators, apply the rescaling to the commutation relation, after which I treat the factor I get from commutator as identity operator instead of this undefined constant? I think I understand what you're saying, but I'm checking if I got it right. Thank you for the response. [/QUOTE]
