Can competition between crystal field and Kondo effect cause non-Fermi liquid like behavior?
Frithjof B. Anders, Thomas Pruschke
The recently reported unusual behavior of the static and dynamical magnetic susceptibility as well as the specific heat in CeLaNiGe has raised the question…
Unusual Non-Fermi Liquid Behavior of CeLaNiGe Analyzed in a Single Impurity Anderson Model with Crystal Field Effects
E. -W. Scheidt, F. Mayr, U. Killer +6
CeNiGe exhibits unusual non-Fermi liquid behavior with the largest ever recorded value of the electronic specific heat JKmol without showin…
Real-time dynamics in Quantum Impurity Systems: A Time-dependent Numerical Renormalization Group Approach
Frithjof B. Anders, Avraham Schiller
We develop a general approach to the nonequilibrium dynamics of quantum impurity systems for arbitrary coupling strength. The numerical renormalization group is used to generate a…
Charge gaps and quasiparticle bands of the ionic Hubbard model
Torben Jabben, Norbert Grewe, Frithjof Anders
The ionic Hubbard model on a cubic lattice is investigated using analytical approximations and Wilson's renormalization group for the charge excitation spectrum. Near the Mott insu…
