Spin-spin correlations between two Kondo impurities coupled to an open Hubbard chain
A. C. Tiegel, P. E. Dargel, K. A. Hallberg +2
In order to study the interplay between Kondo and Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction, we calculate the spin-spin correlation functions between two Kondo impurities co…
Long-range Kondo signature of a single magnetic impurity
Henning Prüser, Martin Wenderoth, Piet E. Dargel +4
The Kondo effect, one of the oldest correlation phenomena known in condensed matter physics, has regained attention due to scanning tunneling spectroscopy (STS) experiments perform…
Adaptive Lanczos-vector method for dynamic properties within the density-matrix renormalization group
P. E. Dargel, A. Honecker, R. Peters +2
Current widely-used approaches to calculate spectral functions using the density-matrix renormalization group in frequency space either necessarily include an artificial broadening…
