Manifestation of many-body interactions in the integer quantum Hall effect regime
Josef Oswald, Rudolf A Römer
We use the self-consistent Hartree-Fock approximation for numerically addressing the integer quantum Hall (IQH) regime in terms of many-body physics at higher Landau levels (LL). T…
Vacancy-driven extended stability of cubic metastable Ta-Al-N and Nb-Al-N phases
Ferdinand Pacher, Paul H. Mayrhofer, David Holec
Quantum mechanical calculations had been previously applied to predict phase stability in many ternary and multinary nitride systems. While the predictions were very accurate for t…
Exchange-mediated dynamic screening in the integer quantum Hall regime
Josef Oswald, Rudolf A. Römer
We study many-body interaction effects in the spatially-resolved filling factor () distribution for higher Landau levels (LLs) via self-consistent Hartree-Fock simulations in th…
Local algorithms for the prime factorization of strong product graphs
Marc Hellmuth, Wilfried Imrich, Werner Klöckl +1
The practical application of graph prime factorization algorithms is limited in practice by unavoidable noise in the data. A first step towards error-tolerant "approximate" prime f…
Cartesian products of directed graphs with loops
Wilfried Imrich, Iztok Peterin
We show that every nontrivial finite or infinite connected directed graph with loops and at least one vertex without a loop is uniquely representable as a Cartesian or weak Cartesi…
