Transport coefficients of dilute magnetic alloys: A quantum Monte Carlo study

Using a new, highly accurate, method of analytic continuation, we provide the first quantitatively correct calculation of the resistivity and thermal conductivity of dilute spin-1/2 magnetic (Anderson and Kondo) alloys over the entire range of interest T≪${\mathit{T}}_{\mathit{K}}$ to T≫${\mathit{T}}_{\mathit{K}}$. We find that our results are consistent with previous approximate theories in their regions of applicability. Our results are the first calculation of transport for any strongly correlated electronic many-body system obtained by direct analytic continuation of Monte Carlo data.
