Quantum entanglement of charges in bound states with finite-size dyons

TL;DR

This paper demonstrates that finite-size monopoles can induce quantum entanglement between charges in bound states, revealing new entangled configurations in a classical Yang-Mills theory model.

Contribution

It introduces the concept of quantum entanglement of charges in bound states involving finite-size dyons within a classical Yang-Mills framework.

Findings

Bound states of scalars and dyons are always entangled.

Energy levels and wave functions of these states are determined.

The stability of the entangled states is discussed.

Abstract

We show that the presence of finite-size monopoles can lead to a number of interesting physical processes involving quantum entanglement of charges. Taking as a model the classical solution of the N=2 SU(2) Yang-Mills theory, we study interaction between dyons and scalar particles in the adjoint and fundamental representation. We find that there are bound states of scalars and dyons, which, remarkably, are always an entangled configuration of the form |\psi > =|dyon+> |scalar-> +/- |dyon->|scalar+>. We determine the energy levels and the wave functions and also discuss their stability.
