Abstract
Due to their relevance for superconducting copper oxides1, models for strongly correlated systems have been studied extensively in last two years. In spite of a number of analytical approaches applied to these models, and to models of the CuO 2 layers in particular, some of the crucial questions lack even a qualitative answer. In such a situation exact diagonalization studies of small correlated systems have proven to be very valuable. Employing this method several groups obtained important results on various models2–10, representing the insulating state and the low doping regime in CuO 2 layers.
