Query: Phase diagram of planar U(1)xU(1) superconductors: condensation of
  vortices with fractional flux and a superfluid state   We discuss a phase diagram of two-dimentional $U(1)\times U(1)$
superconductor in the field theoretic formalizm of Ref. [17]. In particular we
discuss that in the type-I case the system exhibit a quasi-neutral
quasi-superfluid state.
