Intriguing magnetism of Fe monolayers on hexagonal transition-metal surfaces
B. Hardrat, A. Al-Zubi, P. Ferriani +3
Using first-principles calculations, we demonstrate that an Fe monolayer can assume very different magnetic phases on hexagonal hcp (0001) and fcc (111) surfaces of 4d- and 5d-tran…
Maximally Localized Wannier Functions within the FLAPW formalism
F. Freimuth, Y. Mokrousov, D. Wortmann +2
We report on the implementation of the Wannier Functions (WFs) formalism within the full-potential linearized augmented plane wave method (FLAPW), suitable for bulk, film and one-d…
Partial conservation of seniority and nuclear isomerism
P. Van Isacker, S. Heinze
We point out the possibility of the {\em partial} conservation of the seniority quantum number when most eigenstates are mixed in seniority but some remain pure. This situation occ…
Bose-Einstein condensates of atoms with arbitrary spin
P. Van Isacker, S. Heinze
We show that the ground state of a Bose-Einstein condensate of atoms with hyperfine spin f = 2 can be either spin aligned, condensed into pairs of atoms coupled to F = 0, or conden…
Coulomb analogy for nonhermitian degeneracies near quantum phase transitions
P. Cejnar, S. Heinze, M. Macek
Degeneracies near the real axis in a complex-extended parameter space of a hermitian Hamiltonian are studied. We present a method to measure distributions of such degeneracies on t…
