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…

Lanczos algorithm with Matrix Product States for dynamical correlation functions
P. E. Dargel, A. Wöllert, A. Honecker +3
The density-matrix renormalization group (DMRG) algorithm can be adapted to the calculation of dynamical correlation functions in various ways which all represent compromises betwe…
