    "abstract": "The inner crust of a neutron star is a superfluid and inhomogeneous system,\nconsisting of a lattice of nuclei immersed in a sea of neutrons. We perform a\nquantum calculation of the associated pairing gap and compare it to the results\none obtains in the Local Density Approximation (LDA). It is found that the LDA\noverestimates the spatial dependence of the gap, and leads to a specific heat\nof the system which is too large at low temperatures, as compared with the\nquantal result. This is caused by the neglect of proximity effects and the\ndelocalized character of the single-particle wavefunctions close to the Fermi\nenergy. It is possible to introduce an alternative, simple semiclassical\napproximation of the pairing gap which leads to a specific heat that is in good\nagreement with the quantum calculation.",
