Response to the comment on "Do Bloch waves interfere with one another ?"

TL;DR

This paper defends the existence of the Bloch superselection rule against recent criticism, emphasizing the importance of boundary conditions, locality, and topology in solid-state physics.

Contribution

It provides a generalized argument supporting the Bloch superselection rule and refutes recent claims challenging its validity.

Findings

The Bloch superselection rule is upheld under certain boundary conditions.

Locality and topology are crucial in understanding Bloch wave interference.

The recent comment's claim is found untenable based on the presented analysis.

Abstract

Here a generalised argument showing the existence of the Bloch superselection rule is presented, in response to the recent comment by Sowinski. In light of the role played by the periodic boundary condition, locality and topology in the system, the claim made in the comment is found untenable.
