Dirac-Schwinger quantization for emergent magnetic monopoles?
In Refs. [1–4] Dirac and Schwinger showed the existence of a magnetic monopole required a charge quantization condition which we write following Dirac as eg4πħ=n2,n=0,±1,±2,…. Here, g is the magnetic monopole charge and e is the electric charge of the positron. Recently, in Refs. [5,6], it has been...

| Summary: | In Refs. [1–4] Dirac and Schwinger showed the existence of a magnetic monopole required a charge quantization condition which we write following Dirac as eg4πħ=n2,n=0,±1,±2,…. Here, g is the magnetic monopole charge and e is the electric charge of the positron. Recently, in Refs. [5,6], it has been shown experimentally that frustrated spin-ice systems exhibit ‘emergent’ magnetic monopoles. We show that, within the experimental errors, the respective magnetic charges obey the Dirac-Schwinger quantization condition. Possible implications are discussed. |
