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…
