Dynamical Mean-Field Theory on the Real-Frequency Axis: p-d Hybridizations and Atomic Physics in SrMnO
Daniel Bauernfeind, Robert Triebl, Manuel Zingl +2
We investigate the electronic structure of SrMnO with Density Functional Theory (DFT) plus Dynamical Mean-Field Theory (DMFT). Within this scheme the selection of the correlate…
Front dynamics and entanglement in the XXZ chain with a gradient
Viktor Eisler, Daniel Bauernfeind
We consider the XXZ spin chain with a magnetic field gradient and study the profiles of the magnetization as well as the entanglement entropy. For a slowly varying field it is show…
A real-frequency solver for the Anderson impurity model based on bath optimization and cluster perturbation theory
Manuel Zingl, Martin Nuss, Daniel Bauernfeind +1
Recently solvers for the Anderson impurity model (AIM) working directly on the real-frequency axis have gained much interest. A simple and yet frequently used impurity solver is ex…
