Comparison between scattering-states numerical renormalization group and the Kadanoff-Baym-Keldysh approach to quantum transport: Crossover from weak to strong correlations
Sebastian Schmitt, Frithjof B. Anders
The quantum transport through nanoscale junctions is governed by the charging energy of the device. We employ the recently developed scattering-states numerical renormalization…

Dynamic susceptibilities of the single impurity Anderson model within an enhanced non-crossing approximation
Sebastian Schmitt, Torben Jabben, Norbert Grewe
The single impurity Anderson model (SIAM) is studied within an enhanced non-crossing approximation (ENCA). This method is extended to the calculation of susceptibilities and thorou…
