Sažetak
We explore the effect of a (non-)magnetic impurity on the thermal transport of the spin-1/2 Heisenberg chain model. This unique system allows to probe Kondo-type phenomena in a prototype strongly correlated system. Using numerical diagonalization techniques we study the scaling of the frequency dependent thermal conductivity with system size and host-impurity coupling strength as well as the dependence on temperature. We focus in particular on the analysis of “cutting healing” of weak links or a magnetic impurity by the host chain via Kondo-like screening as the temperature is lowered.
