TL;DR

This paper establishes a connection between two-dimensional super-integrable quantum systems and three-body quantum dynamics, revealing how certain potentials and symmetries relate these systems and illustrating with notable examples like the Calogero-Wolfes potential.

Contribution

It introduces a framework linking 2D super-integrable quantum systems to 3-body dynamics, highlighting symmetry reductions and specific potential correspondences.

Findings

2D super-integrable systems relate to 3-body dynamics via symmetry reduction.

Calogero-Wolfes 3-body potential matches 2D quantum dynamics at d=1.

Tremblay-Turbiner-Winternitz potential describes 3-body systems for k=3.

Abstract

It is shown that planar quantum dynamics can be related to 3-body quantum dynamics in the space of relative motion with a special class of potentials. As an important special case the $O(d)$ symmetry reduction from $d$ degrees of freedom to one degree is presented. A link between two-dimensional (super-integrable) systems and 3-body (super-integrable) systems is revealed. As illustration we present number of examples. We demonstrate that the celebrated Calogero-Wolfes 3-body potential has a unique property: two-dimensional quantum dynamics coincides with 3-body quantum dynamics on the line at $d=1$; it is governed by the Tremblay-Turbiner-Winternitz potential for parameter $k=3$.
