Nuclear magnetic resonance at up to 10.1 Giga-Pascal pressure detects an electronic topological transition in aluminum metal
Thomas Meissner, Swee K. Goh, Jürgen Haase +3
High-sensitivity Al nuclear magnetic resonance (NMR) measurements of aluminum metal under hydrostatic pressure of up to 10.1 GPa reveal an unexpected negative curvature in t…
The effect of chemical disorder on the magnetic anisotropy of strained Fe-Co films
Carsten Neise, Stephan Schönecker, Manuel Richter +2
Strained Fe-Co films have recently been demonstrated to exhibit a large magnetocrystalline anisotropy (MCA) and thus to be of potential interest as magnetic storage material. Here,…
The absence of surface states for LiFeAs
Alexander Lankau, Klaus Koepernik, Sergey Borisenko +4
We investigate the cleaving behavior of LiFeAs and determine its surface electronic structure by detailed density functional calculations. We show that due to the neutral surface o…
T>0 ensemble state density functional theory revisited
Helmut Eschrig
A logical foundation of equilibrium state density functional theory in a Kohn-Sham type formulation is presented on the basis of Mermin's treatment of the grand canonical state. it…
Calculated Cleavage Behavior and Surface States of LaOFeAs
Helmut Eschrig, Alexander Lankau, Klaus Koepernik
The layered structure of the iron based superconductors gives rise to a more or less pronounced two-dimensionality of their electronic structure, most pronounced in LaOFeAs. A cons…
Exact solutions for a two-electron quantum dot model in a magnetic field and application to more complex systems
Manfred Taut, Helmut Eschrig
We discussed exact solutions of the Schroedinger equation for a two-dimensional parabolic confinement potential in a homogeneous external magnetic field. It turns out that the two-…
