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…
The Laplace method for energy eigenvalue problems in quantum mechanics
Jeremy Canfield, Anna Galler, James K. Freericks
Quantum mechanics has about a dozen exactly solvable potentials. Normally, the time-independent Schroedinger equation for them is solved by using a generalized series solution for…
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…
Orbital and electronic entanglement in quantum teleportation schemes
Anna Galler, Patrik Thunström
With progress towards more compact quantum computing architectures, fundamental questions regarding the entanglement of indistinguishable particles need to be addressed. In a solid…
Schrodinger's original quantum-mechanical solution for hydrogen
Anna Galler, Jeremy Canfield, James K. Freericks
In 1926, Erwin Schrodinger wrote a series of papers that invented wave mechanics and set the foundation for much of the single-particle quantum mechanics that we teach today. In hi…
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…
