Image Charge Effects on Molecular Electronic Levels at Different Surfaces (2009)
Garcia-Lastra, J. M., Rubio, A., Thygesen, K. S.
On the basis of first-principles G$_0$W$_0$ calculations we study how the electronic levels of a physisorbed molecule are renormalized by dynamic image charge effects for a range of metallic and...
Is there a physical meaning of the natural orbitals? Analysis of exactly solvable models (2009)
Helbig, N., Tokatly, I. V., Rubio, A.
We investigate the suitability of natural orbitals as a basis for describing many-body excitations. We analyze to which extend the natural orbitals describe both bound as well as ionized excited...
Exact Kohn-Sham potential of strongly correlated finite systems (2009)
Helbig, N., Tokatly, I. V., Rubio, A.
The dissociation of molecules, even the most simple hydrogen molecule, cannot be described accurately within density functional theory because none of the currently available functionals accounts for...
Femtosecond laser pulse shaping for enhanced ionization (2009)
Castro, A., Rasanen, E., Rubio, A., Gross, E. K. U.
We demonstrate how the shape of femtosecond laser pulses can be tailored in order to obtain maximal ionization of atoms or molecules. For that purpose, we have overlayed a direct-optimization scheme...
Phonon surface mapping of graphite: disentangling quasi--degenerate phonon dispersions (2009)
Grüneis, A., Serrano, J., Bosak, A., Lazzeri, M., Molodtsov, S. L., Wirtz, L., ...
The two-dimensional mapping of the phonon dispersions around the $K$ point of graphite by inelastic x-ray scattering is provided. The present work resolves the longstanding issue related to the...
Distributed Computing in Algebraic Topology: first trials and errors, first programs. ∗ (2008)
M. Pascual, V. Romero, A. Rubio
Nowadays, Internet appears as a suitable tool for performing scientific computations in a distributed collaborative way. One of the fields where this idea can be applied is that of Symbolic...
Ab-initio band structure of doped graphene (2008)
Attaccalite, C., Grüeneis, A., Pichler, T., Rubio, A.
We present an \emph{ab-initio} study of the graphene quasi-particle band structure as function of the doping in G_0 W_0 approximation. We show that the LDA Fermi velocity is substantially...
MANUFACTURABILITY ISSUES OF REDUNDANT NANOGATES (2008)
F. Martorell, S. D. Cotofana, A. Rubio
Predicted device reliability for nanoelectronics indicates that redundant design will be necessary to build reliable nanosystems. The study of such systems requires the evaluation of the error...
A recent work of Schmidt and Springborg on one-dimensional chains of metal atoms has prompted us to use a quantum-chemical model, posed in terms of dimer potential energy curves, to analyze...
INDEX Instruction Set Energy Models & Power Simulator Tools (ARM7TDMI) (2007)

A time-dependent approach to electron pumping in open quantum systems (2007)
Stefanucci, G., Kurth, S., Rubio, A., Gross, E. K. U.
We propose a time-dependent approach to investigate the motion of electrons in quantum pump device configurations. The occupied one-particle states are propagated in real time and used to calculate...

CONAN - a design exploration framework for reliable nano-electronics architectures (2005)
S. Cotofana, A. Schmid, Y. Leblebici, A. Ionescu, O. Soffke, P. Zipf, ...
In this paper we introduce a design methodology that allows the system/circuit designer to build reliable systems out of unreliable nano-scale components. The central point of our approach is a...
Including uncertainty of speech observations in robust speech recognition (2004)
M. C. Benítez, J. C. Segura, A. Torre, J. Ramírez, A. Rubio
Noise compensation methods for speech recognition provide a cleaned version of the speech representation. Usually this cleaned version is the expected value of the speech parameters given the...
Risk factors in adolescence (1999)

Orderings, AC-Theories and Symbolic Constraint Solving (Extended Abstract) (1995)
H. Comon, R. Nieuwenhuis, A. Rubio
We design combination techniques for symbolic constraint solving in the presence of associative and commutative (AC) function symbols. This yields an algorithm for solving AC-RPO constraints (where...
