Abstract

We discuss single particle dynamics of the half-filled 2D Hubbard model at T → 0 calculated within the dynamical cluster approximation, using numerical renormalization group as non-perturbative cluster solver, which requires the use of parallel architectures with large number of processors and memory. In addition, fast temporal storage for large out-of-core matrices is needed. The results obtained indicate that the half-filled 2D Hubbard model at T → 0 is a paramagnetic insulator for all values of the Coulomb interaction U in strong contrast to weak-coupling theories.
