FINITE-SIZE EFFECTS AND THE MIXED QUARK-HADRON PHASE IN NEUTRON-STARS

We demonstrate that the form and location (not the size or spacing) of the energetically preferred geometrical structure of the crystalline quark-hadron mixed phase in a neutron star are very sensitive to finit e size terms beyond the surface term. We consider two independent appr oaches of including further finite size terms, namely, the multiple re flection expansion of the bag model and an effective surface tension d escription. Thus care should be taken in any model requiring detailed knowledge of these crystalline structures.
