Reply to a Comment of M. Continentino on "Universally diverging Gruneisen parameter and the magnetocaloric effect close to quantum critical points"
Lijun Zhu, Markus Garst, Achim Rosch +1
We show that the comment [cond-mat/0408217] by Continentino on our recent paper [PRL 91, 066404 (2003), cond-mat/0212335] reaches incorrect conclusions as the comment wrongly extra…
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-…
Quantum phase transition of Ising-coupled Kondo impurities
Markus Garst, Stefan Kehrein, Thomas Pruschke +2
We investigate a model of two Kondo impurities coupled via an Ising interaction. Exploiting the mapping to a generalized single-impurity Anderson model, we establish that the model…
Optical Conductivity and Pseudo-Momentum Conservation in Anisotropic Fermi Liquids
A. Rosch, N. Andrei
Umklapp scattering determines the conductivity of clean metals. In typical quasi one-dimensional Fermi liquids with an open Fermi surface, certain pseudo-momenta do not decay by 2-…
Transport in Quasi One-Dimensional Systems
A. Rosch
The interplay of Umklapp scattering from a periodic potential and other scattering processes determine the conductivity of (quasi) one-dimensional metals. We show that the transpor…
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…
