  • Asymmetric light transmission by using 2D PT-symmetric photonic nanostructure 

    Turduev, M.; Botey Cumella, Muriel; Herrero Simon, Ramon; Kurt, H.; Staliunas, Kestutis; Giden, I. (Wiley-IEEE Press, 2015)
    Conference report
    Restricted access - publisher's policy
    We propose for the first time a simple realization of a two-dimensional Parity-Time symmetric hexagonal shaped photonic structure composed of honeycomb lattice. The structure has a symmetric periodic modulation of the ...
  • Quantifying sudden changes in dynamical systems using symbolic networks 

    Masoller Alonso, Cristina; Hong, Yanhua; Ayad, Sarah; Gustave, Francois; Barland, Stéphane; Pons Rivero, Antonio Javier; Gómez, Sergio; Arenas, Alex (2015-02-24)
    Article
    Open Access
    We characterize the evolution of a dynamical system by combining two well-known complex systems' tools, namely, symbolic ordinal analysis and networks. From the ordinal representation of a time series we construct a network ...
  • Ultrashort pulse chirp measurement via transverse second-harmonic generation in strontium barium niobate crystal 

    Trull Silvestre, José Francisco; Sola, Ïñigo; Wang, Bingxia; Parra, Albert; Krolikowski, W.; Sheng, Y.; Vilaseca Alavedra, Ramon; Cojocaru, Crina (2015-06-01)
    Article
    Open Access
    Pulse compression in dispersive strontium barium niobate crystal with a random size and distribution of the anti-parallel orientated nonlinear domains is observed via transverse second harmonic generation. The dependence ...
  • Solvation dynamics in liquid water: 1: ultrafast energy fluxes 

    Rey Oriol, Rosendo; Hynes, James T. (2015-01-30)
    Article
    Restricted access - publisher's policy
    Solvation dynamics in liquid water is addressed via nonequilibrium energy-transfer pathways activated after a neutral atomic solute acquires a unit charge, either positive or negative. It is shown that the well-known ...
  • The limit of mechanical stability in quantum crystals: a diffusion Monte Carlo study of solid He-4 

    Cazorla Silva, Claudio; Boronat Medico, Jordi (2015-07-01)
    Article
    Restricted access - publisher's policy
    We present a first-principles study of the energy and elastic properties of solid helium at pressures below the range in which it is energetically stable. We find that the limit of mechanical stability in hcp He is bar, ...
  • High-accuracy determination of the 238U/ 235U fission cross section ratio up to ˜ 1 GeV at n_TOF at CERN 

    Paradela, C.; Calviani, Marco; Tarrío, D.; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Gómez Hornillos, María Belén; Pretel Sánchez, Carme; Riego Pérez, Albert (2015-02-09)
    Article
    Open Access
    The U238 to U235 fission cross section ratio has been determined at n_TOF up to ˜1 GeV, with two different detection systems, in different geometrical configurations. A total of four datasets has been collected and compared. ...
  • Analysis of the occurence of extreme temperatures in the Iberian Peninsula in a recent 20-year period 

    Mohammed, Ali Jasim; Alarcón Jordán, Marta (2015)
    Conference lecture
    Open Access
    The occurrence of heat waves and cold spells is having a special attention in the last years due to their impact in human health, ecosystems and other aspects such as economy. This work focuses in the analysis of the extreme ...
  • Analysis of extreme rainfall in the Ebre Observatory (Spain) 

    Pérez Zanón, Núria; Casas Castillo, M. del Carmen; Rodríguez Solá, Raúl; Peña, Juan Carlos; Rius, Anna; Solé, J. Germán; Redaño Xipell, Angel (2015-04-25)
    Article
    Restricted access - publisher's policy
    Relationship between maximum rainfall rates for time intervals between 5 minutes and 24 hours has been studied from almost a century (1905-2003) of rainfall data registered in the Ebre Observatory (Tarragona, Spain). ...
  • Generalized equipartition theorem and confining walls 

    Rey Oriol, Rosendo (2015-06)
    Article
    Open Access
    It is shown that the generalized equipartition theorem as applied to the momentum may fail, even though the usual conditions of validity are met. This failure is linked to the nature of the confining walls, with ideal walls ...
  • A Chandrasekhar mass progenitor for the type Ia supernova remnant 3C 397 from the enhanced abundances of nickel and manganese 

    Yamaguchi, H; Badenes, Carles; Foster, Adam; Bravo Guil, Eduardo; Williams, Brian; Maeda, Keichi; Nobukawa, Masayoshi; Eriksen, Kristoffer; Brickhouse, Nancy; Petre, Robert; Koyama, Katsuyi (2015-03-12)
    Article
    Restricted access - publisher's policy
    Despite decades of intense efforts, many fundamental aspects of Type Ia supernovae (SNe Ia) remain elusive. One of the major open questions is whether the mass of an exploding white dwarf (WD) is close to the Chandrasekhar ...
