Physical Review A

Comment on ‘‘Hydrogen atom in one dimension’’

Abstract

In a recent paper Boya, Kmiecik, and Bohm [Phys. Rev. A 37, 3567 (1988)] discuss the one-dimensional hydrogen atom and mention what one should take if one wants to form parity eigenfunctions. In this Comment we show that such even and odd superpositions cannot represent physical states due to a superselection rule that leads to spontaneous breaking of the symmetry of inversion through the origin.

Superselection rule in the one-dimensional hydrogen atom

Comment on 'Fisher information for quasi-one-dimensional hydrogen atom'

O. Olendski

A further argument is provided in the discussion on the correct form of the bound-state momentum wave function of the quasi-one-dimensional hydrogen atom; namely, considering its behavior at the large quantum indices, it is reconfirmed that the complex expression from Olendski (2017) {\it Eur. J. Phys.} {\bf 38} 038001 is a correct one. Groundlessness of other interpretations is also highlighted.

Comment on ‘Limitations on the superposition principle: superselection rules in non-relativistic quantum mechanics’

Namit Anand

This is a comment to the paper, Limitations on the superposition principle: superselection rules in non-relativistic quantum mechanics by C Cisneros et al 1998 Eur. J. Phys. 19 237. doi:10.1088/0143-0807/19/3/005. The proof that the authors construct for the limitation on the superposition of state vectors corresponding to different sectors of the Hilbert space, partitioned by a superoperator has a flaw as outlined below.

The one-dimensional hydrogen atom in momentum representation

H. N. Núñez‐Yépez, Carlos Alejandro Vargas, A. L. Salas Brito

A momentum representation treatment of the one-dimensional hydrogen atom with Coulomb interaction is presented. The authors obtain the energy levels and bound-state eigenfunctions for the problem and discuss the general properties of the solution. The energy spectrum is discrete and given by the Balmer formula. They show that, despite the symmetry of the potential, it is impossible to find eigenfunctions with definite parity for the system.
