| We show that superconductors with inhomogeneous order parameters can show similar features as anisotropic ones. In this paper, we study the low temperature specific heat dependence in such a system and we show that the disorder associated with randomly distributed attractive centers convert the BCS temperature exponential behavior into a power law formula. To describe superconductivity we used a random version of the negative U Hubbard model, while the disorder was treated by means of the coherent potential approximation. |
