    Multi-layered networks represent a major advance in the description of natural complex systems, and their study has shed light on new physical phenomena. Despite its importance, however, the role of the temporal dimension ...
  • Dipolar Bose Supersolid Stripes

    We study the superfluid properties of a system of fully polarized dipolar bosons moving in the XY plane. We focus on the general case where the polarization field forms an arbitrary angle a with respect to the Z axis, ...
  • Field theory for a reaction-diffusion model of quasispecies dynamics

    RNA viruses are known to replicate with extremely high mutation rates. These rates are actually close to the so-called error threshold. This threshold is in fact a critical point beyond which genetic information is lost ...
  • Bose polarons in ultracold atoms in one dimension: beyond the Fröhlich paradigm 

    Grusdt, Fabian; Astrakharchik, Grigori; Demler, Eugene (2017-10-25)
    Artículo

    Mobile impurity atoms immersed in Bose–Einstein condensates provide a new platform for exploring Bose polarons. Recent experimental advances in the field of ultracold atoms make it possible to realize such systems with ...
  • Relating topological determinants of complex networks to their spectral properties: structural and dynamical effects 

    Castellano, Claudio; Pastor Satorras, Romualdo (2017-10-27)
    Artículo
    Acceso abierto
    The largest eigenvalue of a network’s adjacency matrix and its associated principal eigenvector are key elements for determining the topological structure and the properties of dynamical processes mediated by it. We present ...
  • Edge dislocations as sinks for sub-nanometric radiation induced defects in a-iron 

    Anento Moreno, Napoleón; Malerba, L.; Serra Tort, Ana María (Elsevier, 2018-01)
    Artículo
