Fractional charges and Misner-Wheeler charge without charge effect in metamaterials

TL;DR

This paper demonstrates how engineered metamaterials can emulate higher-dimensional theories, enabling the simulation of fractional charges and Misner-Wheeler charge effects through designed topological changes.

Contribution

It introduces a method to replicate fractional and Misner-Wheeler charges in optical metamaterials by manipulating their topology and emulating Kaluza-Klein theory.

Findings

Electromagnetic wormholes alter optical topology.

Fractional charges emerge from topology changes.

Misner-Wheeler charge without charge can be simulated.

Abstract

Optical space in metamaterials may be engineered to emulate four dimensional Kaluza-Klein theory. Nonlinear optics of such metamaterials mimics interaction of quantized electric charges. An electromagnetic wormhole is designed, which connects two points of such an optical space and changes its effective topology. Electromagnetic field configurations which exhibit fractional charges appear as a result of such topology change. Moreover, such effects as Misner-Wheeler charge without charge may be replicated.
