Real-time dynamics induced by quenches across the quantum critical points in gapless Fermi systems with a magnetic impurity

Christian Kleine, Julian Mußhoff, Frithjof B. Anders

The energy-dependent scattering of fermions from a localized orbital at an energy-dependent rate $\Gamma (\epsilon )\propto |\epsilon {|}^r$ gives rise to quantum critical points (QCPs) in the pseudogap s…
