Electron spectra close to a metal-to-insulator transition
Michal Karski, Carsten Raas, Götz S. Uhrig
A high-resolution investigation of the electron spectra close to the metal-to-insulator transition in dynamic mean-field theory is presented. An all-numerical, consistent confirmat…
Spectral Densities from Dynamic Density-Matrix Renormalization
Carsten Raas, Götz S. Uhrig
Dynamic density-matrix renormalization provides valuable numerical information on dynamic correlations by computing convolutions of the corresponding spectral densities. Here we di…
High Energy Dynamics of the Single Impurity Anderson Model
Carsten Raas, Götz S. Uhrig, Frithjof B. Anders
The quantitative control of the dynamic correlations of single impurity Anderson models is essential in several very active fields. We analyze the one-particle Green function with…
Spin-Phonon Chains with Bond Coupling
Carsten Raas, Ute Löw, Götz S. Uhrig +1
We investigate the antiadiabatic limit of an antiferromagnetic S=1/2 Heisenberg chain coupled to Einstein phonons via a bond coupling. The flow equation method is used to decouple…
