    Collective quantum phenomena in the strong light - matter coupling regime 
    Shahnazaryan, Vanik (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-10)
    The physics of light-matter interactions is a rapidly developing interdisciplinary research area, combining methods and phenomena both from condensed matter physics and quantum optics. One of the most common realizations of strong coupling regime implies ...

    Gap Prediction in Hybrid Graphene-Hexagonal Boron Nitride Nanoflakes Using Artificial Neural Networks 
    Nemnes, G. A.; Mitran, T. L.; Manolescu, Andrei (Hindawi Limited, 2019-05-16)
    The electronic properties of graphene nanoflakes (GNFs) with embedded hexagonal boron nitride (hBN) domains are investigated by combined ab initio density functional theory calculations and machine-learning techniques. The energy gaps of the quasi-0D ...

    Influence of Phosphorus on Current Efficiency in Aluminum Electrolysis at Different Current Densities 
    Meirbekova, Rauan; Haarberg, Geir Martin; Thonstad, Jomar; Saevarsdottir, Gudrun Arnbjorg (The Electrochemical Society, 2017)
    Many factors may contribute to loss of current efficiency (CE) in aluminum reduction and one of them is a presence of impurities. In this work, the effect of phosphorus on CE is studied in a laboratory cell at different current densities. Due to a ...

    QM/MM calculations reveal a bridging hydroxo group in a vanadium nitrogenase crystal structure 
    Benediktsson, Bardi; Þórhallsson, Albert Þ.; Bjornsson, Ragnar (Royal Society of Chemistry (RSC), 2018)
    A new 1.2 Å crystal structure of vanadium nitrogenase, isolated under turnover conditions, recently revealed a light atom ligand (OH or NH) replacing the bridging S2B sulfide of the FeV cofactor. QM/MM calculations on the new structure now reveal the ...

    Structure of surface electronic states in strained mercury telluride 
    Kibis, Oleg; Kyriienko, O.; Shelykh, Ivan (IOP Publishing, 2019-04-12)
    We present the theory describing the various surface electronic states arisen from the mixing of conduction and valence bands in a strained mercury telluride (HgTe) bulk material. We demonstrate that the strain-induced band gap in the Brillouin zone ...
