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-…
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…
Fermi and non-Fermi Liquid Behavior in Quantum Impurity Systems: Conserving Auxiliary Particle Theory
J. Kroha, P. Wölfle
We review a recently developed method, based on an exact auxiliary boson representation, to describe both Fermi liquid and non-Fermi liquid behavior in quantum impurity systems. Co…
Magnetic field -induced phase transition in a -wave superconductor at low temperatures
P. J. Hirschfeld, P. Wölfle
We consider, within BCS weak coupling theory, the instability of a -wave superconductor to a state of mixed symmetry , . In zero magnetic field we sh…
Magnetic order and transport in the heavy-fermion system CeCu_{6-x}Au_x
H. v. Löhneysen, A. Neubert, A. Schröder +5
We report on extensive elastic neutron scattering to determine the wave vector of the magnetic order in CeCu_{6-x}Au_x single crystals for x > 0.1. For all values of x investigated…
