We diagonalize exactly the Hamiltonian of the one-dimensional half filled Hubbard model on small clusters of sites with generalized boundary conditions (BCs), and we calculate various correlation functions. We choose the ratio of the onsite repulsion to the hopping matrix element U/t = 1, i.e. an in
The velocity autocorrelatlon function and related quantities are investigated for the onedimensional deterministic Lorentz gas, consisting of randomly distributed fixed scatterers and light particles moving back and forth between two of these at a constant given speed An expansion for the velocity a
