Thank you dRic2, your answers were enlightening!

Your explanation makes sense. In fact, the "momentum" depends on a discrete variable. Even if we approximate this discretization to a continuum (huge amount of electrons and possible states) still wouldn't it make sense to use a description via momentum?

Hello, I wonder if it is possible to write Bloch wave functions in momentum space. To be more specific, it would calculate something like (using Sakurai's notation): $$ \phi(\vec k) = \langle \vec k | \alpha \rangle$$ Moving forward in a few steps: Expanding: $$ \phi(\vec k) = \int d^3\vec r...
