摘要：

The Hubbard model with an intrasite attraction has been recently extensively investigated, as it provides a novel, non-BCS, mechanism of superconductivity, due to the formation of Boson-like electron pairs (intrasite bipolarons) in a real lattice rather than a reciprocal one. The author investigates the collective excitations described by the model using the random phase approximation.
