After being on the cover page of the Journal of Chemical Physics in 2009 Yambo did it again.
The paper Optical characterization of gold chains and steps on the vicinal Si(557) surface: Theory and experiment by Conor Hogan, Niall McAlinden
and John F. McGilp has been choosen as Editor's choice and will appear on the
front page of the Physical Status Solidi b journal.
Stepped surfaces of silicon act as a natural template for engineering one-dimensional nanostructure arrays through self-organization of metal adsorbates. In a joint
experimental-theoretical study, chosen as Editor's Choice and Cover Image for phys. stat. sol (b) (June 2012 issue), Yambo was used to investigate the optical and
electronic properties of clean and gold-covered Si(557), a vicinal Si(111) surface that features densely packed, single atomic gold chains parallel to the step
edge. Using reflectance anisotropy spectroscopy and density functional theory simulations, the authors identified optical "fingerprints" deriving from specific
structural motifs such as gold chains, silicon honeycomb structures, and terrace adatoms. The work will drive a deeper understanding of more complicated double and
triple chain reconstructions of nominal and vicinal Si(111):Au.

In the paper, Yambo was used to apply the GW and
BSE methods, traditionally used in physics applications, to a kind of
system normally studied by quantum chemists by means of (the more
computationally demanding) wavefunction-based approaches, namely,
porphyrin molecules. Yambo yielded excitation spectra in good agreement
with experimental data and with quantum chemical results, and thus offers
chemists an alternative or complementary means for studying such kinds of
