Query: Current correlation functions from a bosonized theory in 3/2+1
  dimensions   Within the context of a bosonized theory, we evaluate the current-current
correlation functions corresponding to a massive Dirac field in 2+1 dimensions,
which is constrained to a spatial half-plane. We apply the result to the
evaluation of induced vacuum currents in the presence of an external field. We
comment on the relation with the purely fermionic version of the model, in the
large-mass limit.
