Taking as a starting-point the development on cooccurrence techniques for several languages, we focus on the aspects that should be considered in a NV extraction task for Basque. In Basque, NV expressions are considered those combinations in which a noun, inflected or not, is co-occurring with a verb, as erabakia hartu (‘to make a decision’), kontuan hartu (‘to take into account’) and buruz jak...

The reflectance of highly reduced SrTiO32x has been studied in samples where the carrier concentration—or oxygen-vacancy density — varies from about 10 to 10 cm. Several phonon modes are strongly influenced by oxygen-vacancy density. Oxygen reduction induces a mid-infrared band whose oscillator strength scales with carrier density. In highly reduced samples, a weakly localized plasmon mode deve...

Following the recent proposal made by [J. Bouttier, Phys. Rev. E 76, 041140 (2007)], we study analytically the mobility properties of a single vacancy in the close-packed dimer model on the square lattice. Using the spanning web representation, we find determinantal expressions for various observable quantities. In the limiting case of large lattices, they can be reduced to the calculation of T...

The microscopic mechanism behind the extraordinary ability of ceria to store, release, and transport oxygen is explained on the basis of first-principles quantum mechanical simulations. The oxygen-vacancy formation energy in ceria is calculated for different local environments. The reversible CeO2-Ce2O3 reduction transition associated with oxygen-vacancy formation and migration is shown to be d...

Extensive experiments and calculation have shown that interstitials in p-Si diffuse athermally, leading to the conclusion that vacancy-interstitial pairs, or Frenkel pairs (FPs), either rapidly recombine or dissociate, even at cryogenic temperatures. More recent experiments, however, suggest that FPs persist to 150 K. Here we report first-principles calculations of FP properties and resolve the...

We report the realization of a quantum circuit in which an ensemble of electronic spins is coupled to a frequency tunable superconducting resonator. The spins are nitrogen-vacancy centers in a diamond crystal. The achievement of strong coupling is manifested by the appearance of a vacuum Rabi splitting in the transmission spectrum of the resonator when its frequency is tuned through the nitroge...
