Abstract
- Abstract: We present the first DCA results for the 2D Hubbard model obtained with a suitably extended version of Wilson''s NRG. We discuss the rôle of non-local fluctuations on the spectral properties at for half-filling. In particular, we find that the system is a paramagnetic insulator for all . [Copyright &y& Elsevier]
