Electronic excitations lie at the origin of most of the commonly measured spectra. However,
the first-principles computation of excited states requires a larger effort than ground-state …

We report a series of calculations testing the predictions of the Tran-Blaha functional for the
electronic structure and magnetic properties of condensed systems. We find a general …

Switchable mirrors,, made of thin films of the hydrides of yttrium (YH x), lanthanum (LaH x) or
rare-earth metals exhibit spectacular changes in their optical properties as x is varied from 0 …

Rare-earth (RE) oxyhydride thin films show a color-neutral, reversible photochromic effect at
ambient conditions. The origin of the photochromism is the topic of current investigations …

The ultrasoft pseudopotential calculations are performed for the CaF 2-type dihydrides TiH
2, VH 2, and CrH 2. The calculated lattice constants agree well with the experimental data …

Thin La 1− z Y z H x films, in the composition range 0< z< 1 and 0< x< 3, are studied using x-
ray diffraction, dc resistivity measurements, reflectance-transmittance measurements, and …

Self-consistent full-potential linearized augmented-plane-wave (LAPW) band-structure
calculations are performed for the fluorite-type dihydrides ScH 2, TiH 2, VH 2, YH 2, ZrH 2 …

Multiple line nodes in energy-band gaps are found in semimetals preserving mirror-
reflection symmetry. We classify possible configurations of multiple line nodes with crossing …

The optical transmission of the recently discovered switchable yttrium hydride films is
determined spectroscopically as a function of hydrogen content. This is done during …

Recently it has been discovered that lanthanum, yttrium, and other metal hydride films show
dramatic changes in the optical properties at the metal-insulator transition. Such changes on …
