Doping-dependent charge- and spin-density wave orderings in a monolayer of Pb adatoms on Si(111)
Matteo Vandelli, Anna Galler, Angel Rubio +3
In this work we computed the phase diagram as a function of temperature and doping for a system of lead adatoms allocated periodically on a silicon (111) surface. This Si(111):Pb m…
Relation between crystal structure and optical properties in the correlated blue pigment YInMnO
Valentin Ransmayr, Jan M. Tomczak, Anna Galler
A material's properties and functionalities are determined by its chemical constituents and the atomic arrangement in which they crystallize. For the recently discovered pigment YI…
Electronic structure of rare-earth mononitrides: quasiatomic excitations and semiconducting bands
Anna Galler, Leonid V. Pourovskii
The electronic structure of the rare-earth mononitrides LnN (where Ln=rare-earth), which are promising materials for future spintronics applications, is difficult to resolve experi…
Combining semi-local exchange with dynamical mean-field theory: electronic structure and optical response of rare-earth sesquioxides
James Boust, Anna Galler, Silke Biermann +1
In rare-earth semiconductors, wide ligand and rare-earth 5 bands coexist with localized, partially filled 4 shells. A simultaneous description for both extended and local…
Correlated electronic structure and optical response of rare-earth-based semiconductors
Anna Galler, James Boust, Alain Demourgues +2
Simultaneous occurrence of the Mott and band gap in correlated semiconductors results in a complex optical response with the nature of the absorption edge difficult to resolve both…
Intrinsically weak magnetic anisotropy of cerium in potential hard-magnetic intermetallics
Anna Galler, Semih Ener, Fernando Maccari +5
Cerium-based intermetallics are currently attracting much interest as a possible alternative to existing high-performance magnets containing scarce heavy rare-earth elements. Howev…
The AbinitioDA Project v1.0: Non-local correlations beyond and susceptibilities within dynamical mean-field theory
Anna Galler, Patrik Thunström, Josef Kaufmann +3
The ab initio extension of the dynamical vertex approximation (DA) method allows for realistic materials calculations that include non-local correlations beyond and dynamic…
Towards ab initio calculations with the dynamical vertex approximation
A. Galler, J. Kaufmann, P. Gunacker +3
While key effects of the many-body problem---such as Kondo and Mott physics---can be understood in terms of on-site correlations, non-local fluctuations of charge, spin, and pairin…
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…
Screened moments and absence of ferromagnetism in FeAl
Anna Galler, Ciro Taranto, Markus Wallerberger +5
While the stoichiometric intermetallic compound FeAl is found to be paramagnetic in experiment, standard band-theory approaches predict the material to be ferromagnetic. We show th…
