LDA+DMFT approach to ordering phenomena and the structural stability of correlated materials
J. Kunes, I. Leonov, P. Augustinsky +3
Materials with correlated electrons often respond very strongly to external or internal influences, leading to instabilities and states of matter with broken symmetry. This behavio…
Excitonic condensation of strongly correlated electrons: the case of PrCaCoO
Jan Kunes, Pavel Augustinsky
We use a combination of dynamical mean-field model calculations and LDA+U material specific calculations to investigate the low temperature phase transition in the compounds from t…
Improved Green's Function Measurement for Hybridization Expansion Quantum Monte Carlo
Pavel Augustinský, Jan Kuneš
We present an algorithm for measurement of the Green's function in the hybridization expansion continuous-time quantum Monte-Carlo based on continuous estimators. Compared to the s…
Doping Induced Spin State Transition in LaCoO3: Dynamical Mean-Field Study
P. Augustinsky, V. Krapek, J. Kunes
Hole and electron doped LaCoO3 is studied using dynamical mean-field theory. The one-particle spectra are analyzed and compared to the available experimental data, in particular th…
Multi-orbital simplified parquet equations for strongly correlated electrons
Pavel Augustinsky, Vaclav Janis
We extend an approximation earlier developed by us for the single-impurity Anderson model to a full-size impurity solver for models of interacting electrons with multiple orbitals.…
Kondo behavior in the asymmetric Anderson model: Analytic approach
V Janis, P. Augustinsky
The low-temperature behavior of the asymmetric single-impurity Anderson model is studied by diagrammatic methods resulting in analytically controllable approximations. We first dis…
