Position-dependent exact-exchange energy for slabs and semi-infinite jellium
(American Physical Society, 2009-12)
The position-dependent exact-exchange energy per particle epsilon(x)(z) (defined as the interaction between a given electron at z and its exact-exchange hole) at metal surfaces is investigated, by using either jellium slabs ...
Exchange-Correlation Hole of a Generalized Gradient Approximation for Solids and Surfaces
(American Physical Society, 2009-02)
We propose a generalized gradient approximation (GGA) for the angle- and system-averaged exchange-correlation hole of a many-electron system. This hole, which satisfies known exact constraints, recovers the Perdew-Burke-Ernzerhof ...
Biodiversity of groundwater oligochaetes from a karst unit in northern Iberian Peninsula: ranking subterranean sites for conservation management
(Springer, 2008-03-05)
El presente estudio sugiere que la unidad kárstica de Santa Eufemia-Ereñozar en el norte de la Península Ibérica es un hotspot de biodiversidad para los oligoquetos de aguas subterráneas, debido a (1) la presencia de un ...
