Theory of x-ray absorption spectroscopy for ferrites
Felix Sorgenfrei, Mébarek Alouani, Johan Schött +3
The theoretical calculation of the interaction of electromagnetic radiation with matter remains a challenging problem for contemporary electronic structure methods, i…
Magnetism in AV3Sb5 (A = Cs, Rb, K): Complex Landscape of the Dynamical Magnetic Textures
Debjani Karmakar, Manuel Pereiro, Md. Nur Hasan +10
We have investigated the dynamical magnetic properties of the V-based kagome stibnite compounds by combining the ab-initio calculated magnetic parameters of a spin Hamiltonian like…
Magnetism in AV3Sb5 (Cs, Rb, K): Origin and Consequences for the Strongly Correlated Phases
Md. Nur Hasan, Ritadip Bharati, Johan Hellsvik +10
The V-based kagome systems AV3Sb5 (A = Cs, Rb and K) are unique by virtue of the intricate interplay of non-trivial electronic structure, topology and intriguing fermiology, render…
Ab initio dynamical vertex approximation
Anna Galler, Patrik Thunström, Patrik Gunacker +2
Diagrammatic extensions of dynamical mean field theory (DMFT) such as the dynamical vertex approximation (DA) allow us to include non-local correlations beyond DMFT on all lengt…
Dynamical vertex approximation in its parquet implementation: application to Hubbard nano-rings
A. Valli, T. Schäfer, P. Thunström +5
We have implemented the dynamical vertex approximation (DA) in its full parquet-based version to include spatial correlations on all length scales and in {\sl all} scattering ch…
Chebyshev expansion for Impurity Models using Matrix Product States
Martin Ganahl, Patrik Thunström, Frank Verstraete +2
We improve a recently developed expansion technique for calculating real frequency spectral functions of any one-dimensional model with short-range interactions, by postprocessing…
