Query: London relation and fluxoid quantization for monopole currents in U(1)
  lattice gauge theory   We explore the analogy between quark confinement and the Meissner effect in
superconductors. We measure the response of color-magnetic "supercurrents" from
Dirac magnetic monopoles to the presence of a static quark-antiquark pair in
four dimensional U(1) lattice gauge theory. Our results indicate that in the
confined phase these currents screen the color-electric flux due to the quarks
in an electric analogy of the Meisner effect. We show that U(1) lattice guage
theory obeys both a dual London equation and an electric fluxoid quantization
condition.
