Electric monopole with internal magnetic monopole like structure Academic Article uri icon


  • The minimal coupling of a membrane to external electromagnetic vector potentials is governed by its charge-current three- vector. The latter is derivable from a ``statistical'' gauge field living on the world-manifold. The exclusive spherically symmetric internal configuration is magnetic-monopole-like, intriguingly interpreted as a genuine electric monopole by an outside observer. Electric-charge quantization then follows provided no internal Dirac point singularity exists. The emerging Dirac-type model cannot tolerate a ``statistical'' Chern-Simons term.
