Hydrogen atom in phase space: the Wigner representation

Ludmiła Praxmeyer, Jan Mostowski, Krzysztof Wódkiewicz

The hydrogen atom is a fundamental exactly soluble system for which the Wigner function, being a quantum analogue of the joint probability distribution of position and momentum, is unknown. In this paper, we present an effective method of calculating the Wigner function, for all bound states of the nonrelativistic hydrogen atom. The formal similarity between the eigenfunctions of the nonrelativistic hydrogen atom in the momentum representation and the Klein–Gordon propagator has allowed the calculation of the Wigner function for an arbitrary bound state of the hydrogen atom, using a simple atomic integral as a generator. These Wigner functions for some low-lying states are depicted and discussed.

The Scretching-Schrodinger Equation Applied to the Complete Hydrogen Atom Spectrum

Daniel Scretching

This paper applies the corrected Scretching–Schrödinger Equation (SSE) to the complete bound-state hydrogen atom spectrum. The ordinary Coulomb hydrogen Hamiltonian is retained as the exact benchmark operator, while the Scretching Quantum Chain (SQC) and Maxwell–Scretching Chain (MSC) are imposed as spectroscopic closure relations that connect quantum wavefunction matrix elements to measurable optical quantities, including oscillator strengths, molar absorptivity, Einstein coefficients, and transition frequencies. Using CODATA 2022 constants and the corrected hydrogen 1s→2p1s\rightarrow2p1s→2p radial transition integral, the Lyman-alpha transition is numerically verified with Kν=7.42165600145×10−22 s,K_{\nu}=7.42165600145\times10^{-22}\ \mathrm{s},Kν=7.42165600145×10−22 s, KSSE=7.50174281×10−13 m2 s,K_{\mathrm{SSE}}=7.50174281\times10^{-13}\ \mathrm{m^{2}\,s},KSSE=7.50174281×10−13 m2s, ∣μ∣SQC=3.2804 D,|\mu|_{\mathrm{SQC}}=3.2804\ \mathrm{D},∣μ∣SQC=3.2804 D, and A21=6.26169×108 s−1.A_{21}=6.26169\times10^{8}\ \mathrm{s^{-1}}.A21=6.26169×108 s−1. The corrected analytic hydrogen dipole moment is ∣μ∣analytic=3.2795 D,|\mu|_{\mathrm{analytic}}=3.2795\ \mathrm{D},∣μ∣analytic=3.2795 D, which removes the previously reported 13% discrepancy and confirms close agreement between the SQC closure value and the standard hydrogenic quantum-mechanical result. The paper then extends the corrected SSE framework across the full bound-state hydrogen spectrum by generating the Lyman, Balmer, Paschen, Brackett, Pfund, and Humphreys series from the reduced-mass Rydberg formula. In this application, the SSE does not replace the ordinary Schrödinger solution for hydrogen; instead, it constrains and verifies the standard Coulomb spectrum through spectroscopic closure. Because the hydrogen Coulomb Hamiltonian already reproduces the bound-state spectrum exactly within nonrelativistic quantum mechanics, the SQC correction term is effectively null for hydrogen, VSQC(H)≈0.V_{\mathrm{SQC}}(H)\approx 0.VSQC(H)≈0. Thus, for the hydrogen atom, the Scretching–Schrödinger Equation reduces to the ordinary Schrödinger equation while preserving the SQC and MSC spectroscopic chains as verification layers linking wavefunctions, transition moments, oscillator strengths, Einstein coefficients, and observed spectral frequencies [1–4,12].

One-Dimensional Hydrogen Atom

R. Loudon

The quantum-mechanical system which consists of a particle in one dimension subjected to a Coulomb attraction (the one-dimensional hydrogen atom) is shown to have a ground state of infinite binding energy, all the excited bound states of the system having a twofold degeneracy. The breakdown of the theorem that a one-dimensional system cannot have degeneracy is examined. The treatment illustrates a number of properties common to the quantum mechanics of one-dimensional systems.
