The relaxation and dephasing rates ${\tilde{\Gamma }}_1$ and ${\tilde{\Gamma }}_2$, derived with respect to the magnetic field $h_0$, for the isotropic Kondo model with $V={10}^{-4}D$ and $T_K={10}^{-8}D$. $\frac{\partial {\tilde{\Gamma }}_1}{\partial h_0}$ exhibits a logarithmic enhancement for $\tilde{h}>V$ whereas $\frac{\partial {\tilde{\Gamma }}_2}{\partial h_0}$ is suppressed for $\tilde{h}<V$.Reuse & Permissions

The rate ${\tilde{\Gamma }}_1$, derived with respect to the magnetic field, as function of the magnetic field at $V={10}^{-4}D$ for the isotropic Kondo model (solid line) and the anisotropic Kondo model with two different values of $c^2={\left(J^z\right)}^2-{\left(J^{\perp }\right)}^2$ (dashed and dash-dotted lines). The Kondo temperature $T_K={10}^{-8}D$ is the same in all cases.Reuse & Permissions
