TL;DR

This paper demonstrates that planar topological gauge theories with dynamics exhibit Efimov-like resonances due to angular momentum corrections from interactions with massive fermions, suggesting observable effects in planar systems.

Contribution

It reveals the emergence of Efimov-like resonances in planar topological gauge theories with dynamical fermions, extending understanding of angular momentum effects beyond topological photon spin.

Findings

Identification of Efimov-like shallow resonances in planar gauge theories

Angular momentum corrections from fermion interactions influence resonance formation

Potential for experimental verification in planar physical systems

Abstract

It is shown that planar topological effective gauge theory with dynamics, acquires corrections to angular momentum beyond the well-known topological photon spin, the latter arising from interactions with parity-breaking massive fermions. In the non-relativistic limit, a first quantized Schroedinger representation is possible where the topological and kinetic terms decouple, the latter contributing to angular momentum and compete with the centrifugal barrier. This results in shallow resonances of Efimov kind, which may be verified in planar physical systems.
