A surface plasmon polariton analogue of a Wannier-Stark ladder
into the vacuum, as functions of its frequency consist of N equally spaced dips and peaks, respectively, that have the form of a Wannier-Stark ladder. By using an analytical approach we show that the localized states with ...

Crystal field and magnetism with Wannier functions: Orthorhombic rare-earth manganites
The crystal field parameters of seven R3+ions (R=Pr, Nd, Sm, Eu, Gd,Tb,Dy) in RMnO3 perovskites were calculated using the combination of the band structure and Wannier function calculations. Inserting the crystalfield obtained in th...

Crystal field parameters with Wannier functions: application to Nd2Fe14B systems
A new method to calculate the crystal field parameters (CFPs) is first applied to crystalline Nd2Fe14B as the representative of rare-earth iron boron permanent magnets. The CFPs are extracted from the one electron Hamiltonian expressed in the basis o...
