  • Interaction of He and He-V clusters with self-interstitials and dislocations defects in bcc Fe 

    Terentyev, Dimitry; Anento Moreno, Napoleón; Serra Tort, Ana María; Ortiz, C. J.; zhurkin, E. E. (2015-03-01)
    Article

    The understanding of helium effects in synergy with radiation damage is crucial for the development of structural steels for fusion applications. Recent investigations in ultra-pure iron, taken as a basic model, have shown ...
  • Evolution of matrix-twin interfaces of (101¯2) twin in magnesium 

    Ostapovets, Andriy; Serra Tort, Ana María (2015-10-01)
    Article
    Restricted access - publisher's policy
    Recently, the presence of basal-prismatic interfaces in hexagonal close packed metals became subject of intensive investigation. We model the {101¯2} twin in magnesium bounded by two types of boundaries, i.e. {101¯2} ...
  • Slow relaxation dynamics and aging in random walks on activity driven temporal networks 

    Sousa da Mata, Angelica; Pastor Satorras, Romualdo (Springer, 2015-02-04)
    Article
    Open Access
    We investigate the dynamic relaxation of random walks on temporal networks by focusing in the recently proposed activity driven model [N. Perra, B. Gon, calves, R. Pastor-Satorras, A. Vespignani, Sci. Rep. 2, 469 (2012)]. ...
  • Insights into Q2Qbar2 states from an effective perspective 

    Ametller Congost, Lluís; Talavera Sánchez, Pedro (American Physical Society, 2015-10-07)
    Article
    Open Access
    We discuss the two-photon coupling of the lightest scalar meson on the basis of an extension of χPT. Using low-energy data on the pion form factor and the γγ→π+π−(π0π0) cross sections as inputs, we find Γ(σ→γγ)≅0.126  keV. ...
  • Epidemic processes in complex networks 

    Pastor Satorras, Romualdo; Castellano, Claudio; Van Mieghem, Piet; Vespignani, Alessandro (2015-08-31)
    Article
    Open Access
    In recent years the research community has accumulated overwhelming evidence for the emergence of complex and heterogeneous connectivity patterns in a wide range of biological and sociotechnical systems. The complex ...
  • Reentrant behavior of the breathing-mode-oscillation frequency in a one-dimensional Bose gas 

    Gudyma, A; Astrakharchik, Grigori; Zvonarev, Mikhail (2015-08-07)
    Article
    Open Access
    Exciting temporal oscillations of the density distribution is a high-precision method for probing ultracold trapped atomic gases. Interaction effects in their many-body dynamics are particularly puzzling and counter-intuitive ...
  • Hydrogen bonding and related properties in liquid water: a Car-Parrinello molecular dynamics simulation study 

    Guàrdia Manuel, Elvira; Skarmoutsos, Ioannis; Masia, Marco (2015-07-23)
    Article
    Open Access
    The local hydrogen-bonding structure and dynamics of liquid water have been investigated using the Car-Parrinello molecular dynamics simulation technique. The radial distribution functions and coordination numbers around ...
  • Proton transfer in liquid water confined inside graphene slabs 

    Tahat, Amani; Martí Rabassa, Jordi (2015-09-09)
    Article
    Open Access
    The microscopic structure and dynamics of an excess proton in water constrained in narrow graphene slabs between 0.7 and 3.1 nm wide has been studied by means of a series of molecular dynamics simulations. Interaction of ...
  • Specific ion binding at phospholipid membrane surfaces 

    Martí Rabassa, Jordi; Calero Borrallo, Carles; Bonomi, Massimiliano; Yang, Jing (2015-08-18)
    Article
    Restricted access - publisher's policy
    Metal cations are ubiquitous components in biological environments and play an important role in regulating cellular functions and membrane properties. By applying metadynamics simulations, we have performed systematic ...
  • 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 ...
