The Coulomb potential and the paradoxes of PT symmetrization

  • Miloslav Znojil


In a parallel to the standard quantum version of the Coulomb/Kepler problem, an alternative Coulomb/Kepler quantum model is formulated and solved. The new model is shown to exhibit not too dissimilar phenomenological (i.e., spectral and scattering) as well as mathematical (i.e., exact-solvability) properties. The paper is made self-contained by explaining the underlying innovative quantization strategy that assigns an entirely new role to symmetries.
