  • Conceptual design of a hybrid neutron-gamma detector for study of ß-delayed neutrons at the RIB facility of RIKEN 

    Tarifeño Saldivia, Ariel Esteban; Taín, J.L.; Domingo Pardo, César; Calviño Tavares, Francisco; Cortés Rossell, Guillem Pere; Phong, V.H.; Riego Pérez, Albert; Agramunt Ros, Jorge; Algora, A. (2017-04-07)
    Article
    Accés restringit per política de l'editorial
    The conceptual design of the BRIKEN neutron detector at the radioactive ion beam factory (RIBF) of the RIKEN Nishina Center is reported. The BRIKEN setup is a complex system aimed at detecting heavy-ion implants, ß particles, ...
  • Influence of liquid crystalline phases on the tunability of a random laser 

    Trull Silvestre, José Francisco; Salud Puig, Josep; Díez Berart, Sergio; López Pérez, David Orencio (American Chemical Society (ACS), 2017-05-30)
    Article
    Accés restringit per política de l'editorial
    In this paper, we report the temperature behavior of an optimized disordered photonic system-based liquid crystal by means of heat capacity and refractive index measurements. The scattering system is formed by a porous ...
  • Nonsingular black holes, the cosmological constant and asymptotic safety 

    Torres Herrera, Ramon (2017-06-05)
    Article
    Accés obert
    Quantum gravitational effects in black hole spacetimes with a cosmological constant ¿ are considered. The effective quantum spacetimes for the black holes are constructed by taking into account the renormalization group ...
  • Non-singular quantum improved rotating black holes and their maximal extension 

    Torres Herrera, Ramon (2017-06-01)
    Article
    Accés restringit per política de l'editorial
    We add a prescription to the Newman–Janis algorithm in order to use it as a means of finding new extended rotating black hole spacetimes from static spherically symmetric ones. Then, we apply the procedure to a quantum ...
  • Rainbow trapping in a chirped three-dimensional photonic crystal 

    Hayran, Zeki; Kurt, Hamza; Staliunas, Kestutis (Macmillan Publishers, 2017-06-08)
    Article
    Accés obert
    Light localization and intensity enhancement in a woodpile layer-by-layer photonic crystal, whose interlayer distance along the light propagation direction is gradually varied, has been theoretically predicted and ...
  • Performance evaluation of a floating lidar buoy in nearshore conditions 

    Gutiérrez Antuñano, Miguel Ángel; Tiana Alsina, Jordi; Rocadenbosch Burillo, Francisco (2017-05-29)
    Article
    Accés restringit per política de l'editorial
    This work provides a signal-processing and statistical-error analysis methodology to assess key performance indicators for a floating Doppler wind lidar. The study introduces the raw-to-clean data processing chain, error ...
  • A study of the air-sea interaction in the South Atlantic Convergence Zone through Granger causality 

    Tirabassi, Giulio; Masoller Alonso, Cristina; Barreiro, Marcelo (Wiley, 2015-10-01)
    Article
    Accés obert
    Air-sea interaction in the region of the South Atlantic Convergence Zone (SACZ) is studied using Granger causality (GC) as a measure of directional coupling. Calculation of the area weighted connectivity indicates that the ...
  • Roadmap on optical rogue waves and extreme events 

    Akhmediev, N; Kibler, Bertrand; Baronio, Fabio; Masoller Alonso, Cristina (Institute of Physics (IOP), 2016-04-26)
    Article
    Accés obert
    The pioneering paper 'Optical rogue waves' by Solli et al (2007 Nature 450 1054) started the new subfield in optics. This work launched a great deal of activity on this novel subject. As a result, the initial concept has ...
  • Complexity and predictability of the monthly Western Mediterranean oscillation index 

    Lana Pons, Francisco Javier; Burgueño Rivero, August; Martínez Santafé, Maria Dolors; Serra de Larrocha, Carina (Wiley, 2016-05)
    Article
    Accés obert
    The complexity, predictability and predictive instability of the Western Mediterranean Oscillation index (WeMOi) at monthly scale, years 1856-2000, are analysed from the viewpoint of monofractal and multifractal theories. ...
  • Self-collimation in PT -symmetric crystals 

    Ahmed Waseem, Waqas Waseem; Herrero Simon, Ramon; Botey Cumella, Muriel; Staliunas, Kestutis (AMER PHYSICAL SOC, 2017-05-10)
    Article
    Accés obert
    We predict the self-collimation phenomena (or equivalently, dynamical localization) in two-dimensional PT-symmetric complex potentials, where the complex modulation is considered in the transverse, longitudinal, or ...
