Identifying an effective model for the two-stage-Kondo regime: Numerical renormalization group results
P. A. Almeida, E. Vernek, E. V. Anda +2
A composite impurity in a metal can explore different configurations, where its net magnetic moment may be screened by the host electrons. An example is the two-stage Kondo (TSK) s…

The cumulant Green's functions method for the single impurity Anderson model
T. M. Sobreira, T. O. Puel, M. A. Manya +5
Using the cumulant Green's functions method (CGFM), we study the single impurity Anderson model (SIAM). The CGFM starting point is a diagonalization of the SIAM Hamiltonian express…
