    Current interest in barocaloric effects has been stimulated by the discovery that these pressure-driven thermal changes can be giant near ferroic phase transitions in materials that display magnetic or electrical order. ...
  • Limit cycle bifurcations in resonant LC power inverters under zero current switching strategy 

    Benadero García-Morato, Luis; Ponce, Enrique; El Aroudi, Abdelali; Torres Peral, Francisco (2017-11-22)
    Article
    Accés restringit per política de l'editorial
    The dynamics of a DC-AC self-oscillating LC resonant inverter with a zero current switching strategy is considered in this paper. A model that includes both the series and the parallel topologies and accounts for parasitic ...
  • Insight into the dynamics of low temperature dielectric relaxation of ordinary perovskite ferroelectrics 

    Levit Valenzuela, Rafael; Ochoa Guerrero, Diego A.; Martínez García, Julio Cesar; García García, José Eduardo (2017-11-10)
    Article
    Accés obert
    The temperature dependence of the dielectric response of ordinary ferroelectric materials exhibits a frequency-independent anomalous peak as a manifestation of the ferroelectric to paraelectric phase transition. A second ...
  • Bose polarons in ultracold atoms in one dimension: beyond the Fröhlich paradigm 

    Grusdt, Fabian; Astrakharchik, Grigori; Demler, Eugene (2017-10-25)
    Article
    Accés obert
    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)
    Article
    Accés obert
    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 ...
  • Extensional channel flow revisited: a dynamical systems perspective 

    Marqués Truyol, Francisco; Meseguer Serrano, Álvaro; Mellibovsky Elstein, Fernando; Weidman, Patrick (2017-06-07)
    Article
    Accés obert
    Extensional self-similar flows in a channel are explored numerically for arbitrary stretching–shrinking rates of the confining parallel walls. The present analysis embraces time integrations, and continuations of steady ...
  • An enduring rapidly moving storm as a guide to Saturn's Equatorial jet's complex structure

    Roca Cazorla, David; Lloberas Valls, Oriol; Cante Terán, Juan Carlos; Oliver Olivella, Xavier (2017-11)
    Article
    Accés obert
    A framework, based on an extended Hill–Mandel principle accounting for inertial effects (Multiscale Virtual Work principle), is developed for application to acoustic problems in the context of metamaterials modelling. The ...
  • Multiband study of RX J0838-2827 and XMM J083850.4-282759: a new asynchronous magnetic cataclysmic variable and a candidate transitional millisecond pulsar 

    Rea, N.; de Martino, Domitilla; Israel, G; Bozzo, Enrico; Linares Alegret, Manuel; Hernanz Carbó, Margarita; Casares, Jorge (2017-11-01)
    Article
    Accés obert
    In a search for the counterpart to the Fermi-LAT source 3FGL J0838.8-2829, we performed a multiwavelength campaign: in the X-ray band with Swift and XMM-Newton; in the infrared and optical with OAGH, ESO-NTT and IAC80; and ...
  • A planetary-scale disturbance in the most intense Jovian atmospheric jet from JunoCam and ground-based observations 

    Sanchez-Lavega, Agustin; Rogers, John H; Orton, Glenn; García Melendo, Enrique José; Legarreta, Jon; Colas, Françoise; Dauvergne, J; Hueso, Ricardo; Rojas, Jose Félix; Perez-Hoyos, Santiago; Mendikoa, Iñigo; Iñurrigarro, P; Gómez-Forrellad, Josep M.; Momary, T; Hansen, C. J.; Eichstaedt, G.; Miles, P; Wesley, A (2017-05-25)
    Article
    Accés obert
    We describe a huge planetary-scale disturbance in the highest-speed Jovian jet at latitude 23.5°N that was first observed in October 2016 during the Juno perijove-2 approach. An extraordinary outburst of four plumes was ...
  • Scattering properties of a PT dipole 

    Staliunas, Kestutis; Markos, P.; Kuzmiak, V. (2017-10-23)
    Article
    Accés obert
    Electromagnetic response of a PT dipole is studied both analytically and numerically. In the analytical approach, the dipole is represented by two point scatterers. Within the first Born approximation, the asymmetry of the ...
