Comment on "Fano Resonance for Anderson Impurity Systems"
Ch. Kolf, J. Kroha, M. Ternes +1
In a recent Letter, Luo et al. (Phys. Rev. Lett. 92, 256602 (2004)) analyze the Fano line shapes obtained from scanning tunneling spectroscopy (STS) of transition metal impurities…
Nonequilibrium Transport through a Kondo Dot: Decoherence Effects
J. Paaske, A. Rosch, J. Kroha +1
We investigate the effects of voltage induced spin-relaxation in a quantum dot in the Kondo regime. Using nonequilibrium perturbation theory, we determine the joint effect of self-…
Self-consistent Conserving Theory for Quantum Impurity Systems: Renormalization Group Analysis
Stefan Kirchner, Johann Kroha
We review the diagrammatic, conserving theory for quantum impurities with strong on-site repulsion. The method is based on auxiliary particle technique, where Wick's theorem is val…
Fermi and Non-Fermi Liquid Behavior of Quantum Impurity Models: A Diagrammatic Pseudo-particle Approach
J. Kroha, P. Wölfle
We review a systematic many-body method capable of describing Fermi liquid and Non-Fermi liquid behavior of quantum impurity models at low temperatures on the same footing. The cro…
Comment on "Non-equilibrium Electron Distribution in Presence of Kondo Impurities" (cond-mat/0102150v2)
J. Kroha, A. Zawadowski
An inadequate approximation and its consequences as well as an incorrect statement made in cond-mat/0102150v2 are pointed out.
Kondo effect in non-equilibrium - Theory of energy relaxation induced by dynamical defects in diffusive nanowires
Johann Kroha
In diffusive Cu and Au quantum wires at finite transport voltage the non-equilibrium distribution function exhibits scaling behavior, , indicating anom…
