    "abstract": "For the example of the infinitely deep well potential, we point out some\nparadoxes which are solved by a careful analysis of what is a truly\nself-adjoint operator. We then describe the self-adjoint extensions and their\nspectra for the momentum and the Hamiltonian operators in different physical\nsituations. Some consequences are worked out, which could lead to experimental\nchecks.",
