Abstract
A new scheme for the reconstruction and approximation of quantum wave functions is derived within the context of Information Theory. The method is applied to the inference of the energy spectra and the pertinent eigenstates of special hamiltonians from incomplete information concerning the system’s ground state, and to the development of an approximation for the ground state of a superconducting many-fermion model. A substantial improvement over standard and projected BCS approximations is obtained, especially in transitional regions.
