The mass-flow error in the Numerical Renormalization Group method and the critical behavior of the sub-ohmic spin-boson model
Matthias Vojta, Ralf Bulla, Fabian Guettge +1
We discuss a particular source of error in the Numerical Renormalization Group (NRG) method for quantum impurity problems, which is related to a renormalization of impurity paramet…
Interplay between Kondo physics and spin-orbit coupling in carbon nanotube quantum dots
Martin R. Galpin, Frederic W. Jayatilaka, David E. Logan +1
We investigate the influence of spin-orbit coupling on the Kondo effects in carbon nanotube quantum dots, using the numerical renormalization group technique. A sufficiently large…
Multiple-charge transfer and trapping in DNA dimers
Sabine Tornow, Ralf Bulla, Frithjof B. Anders +1
We investigate the charge transfer characteristics of one and two excess charges in a DNA base-pair dimer using a model Hamiltonian approach. The electron part comprises diagonal a…
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…
