Transient dynamics of the Hubbard model with nearest- and next-nearest-neighbor hopping — •Yusuf Mohammed and Alexander I. Lichtenstein — Institute of Theoretical Physics, University of Hamburg, 20355 Hamburg, Germany

We investigate the transient dynamics of the single orbital two-dimensional Hubbard model with nearest- and next-nearest-neighbor hopping. In equilibrium this model has provided a strong-coupling approach to the theory of high-temperature superconductivity as observed in copper oxides. We employ non-equilibrium cluster dynamical mean-field theory (CDMFT), using self-consistent strong-coupling perturbation theory, with the non-crossing approximation (NCA) being the lowest order. We report results for different quench protocols and driving fields.
