  • A polarizable ion model for the structure of molten CuI 

    Bitrian Varea, Vicente; Alcaraz Sendra, Olga; Trullàs Simó, Joaquim (2011-01-24)
    Article
    Open Access
    The results are reported of the molecular dynamics simulations of the coherent static structure factor of molten CuI at 938 K using a polarizable ion model. This model is based on a rigid ion potential to which the many ...
  • Beam focalization in reflection from flat dielectric subwavelength gratings 

    Cheng, Yu Chieh; Zeng, H; Trullàs Simó, Joaquim; Cojocaru, Crina; Malinauskas, Mangirdas; Jukna, T; Wiersma, D.S.; Staliunas, Kestutis (2014-10-15)
    Article

    We experimentally demonstrate the recently predicted effect of near-field focusing for light beams from flat dielectric subwavelength gratings (SWGs). This SWGs were designed for visible light 532 nm and fabricated by ...
  • Br diffusion in molten NaBr explored by coherent quasielastic neutron scattering 

    Demmel, F; Alcaraz Sendra, Olga; Trullàs Simó, Joaquim (AMER PHYSICAL SOC, 2016-04-12)
    Article
    Open Access
    Molten sodium bromide has been investigated by quasielastic neutron scattering focusing on the wave vector range around the first structure factor peak. The linewidth of the scattering function shows a narrowing around the ...
  • Continuous pressure-induced structural transition in the noble-metal halide melts 

    Silbert, Moises; Giró Roca, Antoni; Trullàs Simó, Joaquim (1992-12-01)
    Article
    Open Access
    The reduction of the charge of the species in molten salts, including the complete removal of the Coulomb interaction, appears to have the same effect as an increase in the pressure on these systems. This observation leads ...
