      abstract     = {The recently developed RT-RG approach was applied to study
                      the non-linear transport through a quantum dot described by
                      the Anderson impurity model. The RT-RG equations were solved
                      numerically including both 1- and 2- loop orders in the
                      limit of zero temperature and non-linear transport voltages
                      where most standard theoretical methods break down. We
                      predict non-perturbative tunneling effects in the transport
                      stability diagram which can be measured experimentally.
                      Moreover, we found the exact functional form of the
                      renormalized spectra of the dot at any loop order. In the
                      non-interacting case we show that the RT-RG recovers the
                      exact solution within our 2 loop approach. In the
                      strong-interacting limit the method breaks down as expected
                      only at very small voltages on the order of the Kondo
                      temperature, which we illustrate by comparison with the
                      Friedel sum rule.},
