Abstract
Excited states of Bogoliubov–de Gennes equations are examined for a two-dimensional negative-U Hubbard Hamiltonian with on-site disorder. It is shown explicitly that the temperature (pseudogap temperature) when the superconducting gap opens is different from that (the superconducting transition temperature) where the long-range order appears. In the excited-state solutions the system is self-organized into blocks, which behave like superspins and are coupled with their neighbors. Only if the couplings between these blocks become strong enough can the true long-range order be realized.
