Abstract:

Extrapolations of numerical data obtained from finite cluster calculations to the infinite volume limit can often give incorrect results. We discuss four separate cases a the intensity of the lowest two-photon absorption in the infinite polyene, b bond alternation in the infinite polyene c Cooper type pairing in the simple Hubbard model, and d pairing within the extended Hubbard model.
