The charge susceptibility and the specific heat of the 1D Hubbard model are calculated by means of the composite operator method for finite temperature as functions of filling. A large renormalization of the charge fluctuations appears as the system approaches the metal-insulator transition. © 1999 Elsevier Science B.V. All rights reserved.
