New exact solutions of the 3D Schr\"odinger equation

Abstract:Previously we found a unique quantum system with a positive gauge-invariant Weyl-Stratonovich quasi-probability density function which can be defined by the so-called «quadratic funnel» potential. In this work we have constructed a class of exact solutions to the 3D Schrödinger equation for a two-parameter «quadratic funnel» potential based on the $\Psi$ -model of micro and macro systems. It should be noted that the Aharonov-Bohm effect is inherent in the quantum $\Psi$ -model. Explicit expressions for the energy spectrum and the set of eigenfunctions have been found. Using gauge invariance for scalar and vector potentials, a solution to the electromagnetic Schrödinger equation has been obtained, with a magnetic field in the form of a «Dirac string» defined by a singular vortex probability flux field. Superpositions of eigenfunctions leading to various types of vortex and potential probability current fields have been investigated in detail. The analysis of the quantum system's properties has been carried out within the Wigner-Vlasov formalism.
