  • Mantovan, R.; Fallica, R.; Mokhles Gerami, A.; Mølholt, T. E.; Wiemer, C.; Longo, M.; Gunnlaugsson, Haraldur; Johnston, K.; Masenda, H.; Naidoo, D.; Ncube, M.; Bharuth-Ram, K.; Fanciulli, M.; Gíslason, Hafliði Pétur; Langouche, G.; Olafsson, Sveinn; Weyer, G. (Springer Nature, 2017-08-15)
    The underlying mechanism driving the structural amorphous-to-crystalline transition in Group VI chalcogenides is still a matter of debate even in the simplest GeTe system. We exploit the extreme sensitivity of 57Fe emission Mössbauer spectroscopy, ...
  • Holmlid, Leif; Olafsson, Sveinn (Elsevier BV, 2019-06)
    This work reports identification of muons by their characteristic life-time of 2.20 μs after laser-induction of their precursor mesons, both kaons K± and KL 0 and pions π± in ultra-dense hydrogen H(0). The pair-production signal from scattered muons ...

    A global optimization procedure is used to predict the structure and electronic properties of the b = c[001] edge dislocation in rutile TiO2. Over 1000 different atomic configurations have been generated using both semi-empirical and density functional ...
  • Kateb, Movaffaq; Gudmundsson, Jon Tomas; Ingvarsson, Snorri (AIP Publishing, 2019-03-08)
    We investigate the effect of atomic ordering on the magnetic anisotropy of Ni80Fe20 at.% (Py). To this end, Py films were grown epitaxially on MgO(001) using dc magnetron sputtering (dcMS) and high power impulse magnetron sputtering (HiPIMS). Aside ...
  • Ohlsson, Tommy; Pernow, Marcus (Springer Science and Business Media LLC, 2019-06-18)
    We consider numerical fits to non-supersymmetric SO(10)-based models in which neutrino mass is generated by the type-I or type-II seesaw mechanism or a combination of both. The fits are performed with a sophisticated top-down procedure, taking into ...
  • Morina, Skender; Dini, Kevin Tanguy Elian; Iorsh, Ivan; Shelykh, Ivan (American Chemical Society (ACS), 2018-02-12)
    We propose an experimentally friendly scheme for trapping quasi-relativistic electrons in graphene by an electromagnetic beam with circular polarization and a spatially inhomogeneous profile with an intensity dip. The trapping is achieved due to the ...
