  1. On the exact solutions of a two-dimensional hydrogen atom in a constant magnetic field

    quant-ph 2025-06 conditional novelty 4.0 of 10

    The polynomial quasi-exact solutions for the 2D hydrogen atom in a magnetic field match true eigenstates only at special field strengths, so they are not the full spectrum.
