Functional renormalization-group approaches, one-particle (ir)reducible with respect to local Green functions, using the dynamical mean-field theory as a starting point
A. A. Katanin
We consider formulations of the functional renormaliztion-group flow for correlated electronic systems, having the dynamical mean-field theory as a starting point. We classify the…
Dynamical Vertex Approximation
Karsten Held
Dynamical vertex approximation is a Feynman diagrammatic extension of dynamical mean field theory, including non-local correlations on all time and length scales. Starting with the…
Magnetic exchange in -iron from the ab initio calculations in the paramagnetic phase
P. A. Igoshev, A. V. Efremov, A. A. Katanin
Applying the local density approximation (LDA) and dynamical mean field theory (DMFT) to paramagnetic -iron, we revisit a problem of theoretical description of its magnetic prop…
Correlated starting points for the functional renormalization group
Nils Wentzell, Ciro Taranto, Andrey A. Katanin +2
We present a general frame to extend functional renormalization group (fRG) based computational schemes by using an exactly solvable interacting reference problem as starting point…
Anomalous temperature and field behaviors of magnetization in cubic lattice frustrated ferromagnets
A. N. Ignatenko, A. A. Katanin, V. Yu. Irkhin
Thermodynamic properties of cubic Heisenberg ferromagnets with competing exchange interactions are considered near the frustration point where the coefficient in the spin-wave…
