Hall-effect evolution across a heavy-fermion quantum critical point

S. Paschen, T. Luhmann, S. Wirth +6

A quantum critical point (QCP) develops in a material at absolute zero when a new form of order smoothly emerges in its ground state. QCPs are of great current interest because of…

Transient currents and universal timescales for a fully time-dependent quantum dot in the Kondo regime

Martin Plihal, David C. Langreth, Peter Nordlander

Using the time-dependent non-crossing approximation, we calculate the transient response of the current through a quantum dot subject to a finite bias when the dot level is moved s…

Destruction of the Kondo effect in a multi-channel Bose-Fermi Kondo model

Stefan Kirchner, Lijun Zhu, Qimiao Si

We consider the SU(N) x SU(kappa N) generalization of the spin-isotropic Bose-Fermi Kondo model in the limit of large N. There are three fixed points corresponding to a multi-chann…

Quantum critical properties of the Bose-Fermi Kondo Model in a large-N limit

Lijun Zhu, Stefan Kirchner, Qimiao Si +1

Studies of non-Fermi liquid properties in heavy fermions have led to the current interest in the Bose-Fermi Kondo model. Here we use a dynamical large-N approach to analyze an SU(N…

Dynamical Properties of the Anderson Impurity Model within a Diagrammatic Pseudoparticle Approach

S. Kirchner, J. Kroha, P. Wölfle

The Anderson model of a twofold spin degenerate impurity level in the limit of infinite Coulomb repulsion, , coupled to one and two degenerate conduction bands or cha…
