Query: Crystalline Structure in the Confined-Deconfined Mixed Phase: Neutron
  Stars   We review the differences in first order phase transition of single and
multi-component systems, and then discuss the crystalline structure expected to
exist in the mixed confined deconfined phase of hadronic matter. The particular
context of neutron stars is chosen for illustration. The qualitative results
are general and apply for example to the vapor-liquid transition in
subsaturated asymmetric nuclear matter.
