Comment on “Do Bloch waves interfere with one another?”

We point out that argumentation presented in [Phys. Lett. A 417, 127699 (2021)], leading to the conclusion periodic systems there is a superselection principle forbidding two different Bloch states form coherent superposition of fixed phase, unjustified and false. As an example, we show operator projecting selected Wannier state can be experimentally utilized determine relative phase between superposed states. In this way argue that, fact, non-existence aforementioned manifested always when localized measurements are performed, for example state-of-the-art experiments with ultracold atoms confined optical lattices.
