We investigate the fluctuation contribution to the specific heat of a two-dimensional superconductor with a non-Fermi normal state described by a Anderson Green's function [Formula: see text]. The specific heat corrections contain a term proportional to [Formula: see text] and another logarithmic one. We define a coherence length as function of the non-Fermi paramter α, which shows that a crossover study between BCS and Bose-Einstein condensation is possible by varying the non-Fermi parameter α.
