Directional scrambling of quantum information in helical multiferroics
M. Sekania, M. Melz, N. Sedlmayr +2
Local excitations as carriers of quantum information spread out in the system in ways governed by the underlying interaction and symmetry. Understanding this phenomenon, also calle…
-hole Pockets of the Palladium Fermi Surface Revealed by Positron Annihilation Spectroscopy
Michael Sekania, Andreas Östlin, Wilhelm H. Appelt +2
Using the combined Density Functional and Dynamical Mean Field theory we study relativistic corrections to the Fermi surface of palladium. We find indeed that relativistic correcti…
Magnetic Compton profiles of Ni beyond the one-particle picture: numerically exact and perturbative solvers of dynamical mean-field theory
A. D. N. James, M. Sekania, S. B. Dugdale +1
We calculated the magnetic Compton profiles (MCPs) of Ni using density functional theory supplemented by electronic correlations treated within dynamical mean-field theory (DMFT).…
Lattice dynamics of palladium in the presence of electronic correlations
W. H. Appelt, A. Östlin, I. Di Marco +4
We compute the phonon dispersion, density of states, and the Grüneisen parameters of bulk palladium in the combined density functional theory (DFT) and dynamical mean-field theory…
Mass-Imbalanced Ionic Hubbard Chain
Michael Sekania, Dionys Baeriswyl, Luka Jibuti +1
A repulsive Hubbard model with both spin-asymmetric hopping () and a staggered potential (of strength ) is studied in one dimension. The model is…
Braiding errors in interacting Majorana quantum wires
Michael Sekania, Stephan Plugge, Martin Greiter +2
Avenues of Majorana bound states (MBSs) have become one of the primary directions towards a possible realization of topological quantum computation. For a Y-junction of Kitaev quan…
