Singapore Management University's School of Information Systems is a young school within a young and small university in Asia. Being young and small, establishing a successful analytics master degree program required extensive landscape research, assessment of its own strengths and weaknesses,...

This article aims to scrutinize an emerging and prominent type of work team in organizations: the spontaneous virtual team (SVT). Despite the promising benefits an SVT can provide, it is confronted with great challenges throughout its lifecycle. In this article, we first highlight the unique...

We report key advances in the area of GW calculations, review the available software implementations and define standardization criteria to render the comparison between GW calculations from different codes meaningful, and identify future major challenges in the area of quasiparticle...

We present a systematic study of the performance of numerical pseudo-atomic orbital basis sets in the calculation of dielectric matrices of extended systems using the self-consistent Sternheimer approach of [F. Giustino et al., Phys. Rev. B <Emphasis Type="Bold">81, 115105 (2010)]. In order to cover a range of...</emphasis>

The electronic properties of three different oxides (ZnO, SnO<Subscript>2</Subscript> and SiO<Subscript>2</Subscript>) are investigated within many-body perturbation theory in the G <Superscript>0</Superscript> W <Superscript>0</Superscript> approximation. The frequency dependence of the dielectric function is either approximated using two different well-established plasmon-pole models (one of...</superscript></superscript></subscript></subscript>

It has been recently shown, using ab-initio methods, that bulk diamond is characterized by a large band-gap renormalization (∼0.6 eV) induced by the electron-phonon interaction. In this work we show that in polymers, compared to bulk materials, the larger amplitude of the atomic vibrations...

In a recent publication [J.A. Berger, L. Reining, F. Sottile, Phys. Rev. B <Emphasis Type="Bold">82, 041103(R) (2010)] we introduced the effective-energy technique to calculate in an accurate and numerically efficient manner the GW self-energy as well as the polarizability, which is required to evaluate the screened...</emphasis>

Using many-body perturbation theory within a G <Subscript>0</Subscript> W <Subscript>0</Subscript> approximation, with a plane wave basis set and using a starting point based on density functional theory within the generalized gradient approximation, we explore routes for computing the ionization potential (IP), electron affinity (EA), and...</subscript></subscript>
