Spin-lattice relaxation rate of a magnetic impurity in the spin degenerate Anderson model
J. W. M. Pinto, H. O. Frota
The renormalization group formalism was applied to calculate the spin-lattice relaxation rate of a well-defined magnetic moment in the neighborhood of a spin degenerate Anderson im…

Tunneling in mesoscopic junctions
H. O. Frota
We have applied the Numerical Renormalization Group method to study a mesoscopic system consisting of two samples of metal separated by an insulating barrier, with nanometer dimens…
