    • Interacción y caracterización de estructuras localizadas en sistemas no lineales 
      Sauma Pérez, Tania Javiera (Universidad de Chile, 2012)
      En esta tesis se estudian dos sistemas fuera del equilibrio: una capa de agua vibrada vertical- mente que exhibe solitones hidrodinámicos no propagativos y un cristal líquido nemático al que se le aplica un campo ...
    • Interaction between vegetation patches and gaps: A self-organized response to wáter scarcity 
      Tlidi, M.; Berríos Caro, E.; Pinto Ramo, D.; Vladimirov, A. G; Clerc Gavilán, Marcel (Elsevier, 2020)
      The dynamics of ecological systems are often described by integrodifferential equations that incorporate nonlocal interactions associated with facilitative, competitive interactions between plants, and seed dispersion. In ...
    • Internal noise and system size effects induce nondiffusive kink dynamics 
      Contreras, Diego; Clerc Gavilán, Marcel (American Physical Society, 2015)
      We investigate the effects of inherent fluctuations and system size in the dynamics of domain between uniform symmetric states. In the case of monotonous kinks, this dynamics is characterized by exhibiting nonsymmetric random ...

      Clerc Gavilán, Marcel; Coullet, Pierre; Rojas, Rene G.; Tlidi, Mustapha (American Institute of Physics, 2020)
      This Focus Issue on instabilities and nonequilibrium structures includes invited contributions from leading researchers across many different fields. The issue was inspired in part by the “VII Instabilities and Nonequilibrium ...
    • Labyrinthine patterns transitions 
      Echeverría Alar, S.; Clerc Gavilán, Marcel (American Physical Society, 2020)
      Macroscopic systems with injection and dissipation of energy exhibit intricate dissipative structures. Labyrinthine patterns are disordered spatial structures arising into homogeneous media that show a short-range order. ...
    • Light-matter interaction induces a shadow vortex 
      Barboza, R.; Bortolozzo, Umberto; Clerc Gavilán, Marcel; Dávila Bonczos, Juan; Kowalczyk, Michal; Residori, S.; Vidal Henríquez, Estefanía (Amer Physical Soc, 2016)
      By sending a light beam on a homeotropic nematic liquid-crystal cell subjected to a voltage with a photosensitive wall, a stable matter vortex can be induced at the center of the beam. When the applied voltage is decreased, ...
    • Liquid-solid-like transition in quasi-one-dimensional driven granular media 
      Clerc Gavilán, Marcel; Cordero Simunovic, Aliro; Dunstan, Jocelyn; Huff, K.; Mujica Fernández, Nicolás; Risso, Dino; Varas, G. (NATURE PUBLISHING GROUP, 2008-03)
      The theory of non-ideal gases at thermodynamic equilibrium, for instance the van der Waals gas model, has played a central role in our understanding of coexisting phases, as well as the transitions between them. In contrast, ...
    • Local theory of the slanted homoclinic snaking bifurcation diagram 
      Bortolozzo, U.; Clerc Gavilán, Marcel; Residori, S. (AMER PHYSICAL SOC, 2008-09)
      Localized states in out of equilibrium one-dimensional systems are described by the homoclinic snaking associated with the infinite sequence of multibump localized solutions of the corresponding time reversible dynamical ...
    • Localized patterns and hole solutions in one-dimensional extended systems 
      Clerc Gavilán, Marcel; Falcón Beas, Claudio (ELSEVIER SCIENCE BV, 2005-10-01)
      he existence, stability properties, dynamical evolution and bifurcation diagram of localized patterns and hole solutions in one-dimensional extended systems are studied from the point of view of front interactions. An ...
    • Localized plateau beam resulting from strong nonlocal coupling in a cavity filled by metamaterials and ... 
      Tlidi, M.; Fernández Oto, C.; Clerc Gavilán, Marcel; Escaff Dixon, Daniel; Kockaert, P. (American Physiological Society, 2015)
      We investigate the formation of a localized plateau beam in the transverse section of a nonlinear optical ring cavity filled with a metamaterial and a nonlocal medium such as a nematic liquid crystal. We show that, far ...
    • Localized states and non-variational Ising Bloch transition of a parametrically driven easy-plane ferromagnetic ... 
      Clerc Gavilán, Marcel; Coulibaly, Saliya; Laroze, David (ELSEVIER, 2010)
      A time-periodic magnetic field applied transversally to the hard axis of an extended easy-plane ferromagnetic sample can produce parametric resonance. For the 2:1 resonance, the prototype orderparameter- equation derived ...
    • Localized states beyond the asymptotic parametrically driven amplitude equation 
      Clerc Gavilán, Marcel; Coulibaly, S.; Laroze, David (AMER PHYSICAL SOC, 2008-05)
      We study theoretically a family of localized states which asymptotically connect a uniform oscillatory state in the magnetization of an easy-plane ferromagnetic spin chain when an oscillator magnetic field is applied ...
    • Localized states in bistable pattern-forming systems 
      Bortolozzo, U.; Clerc Gavilán, Marcel; Falcón Beas, Claudio; Residori, S.; Rojas, R. (AMERICAN PHYSICAL SOC, 2006-06)
      We present a unifying description close to a spatial bifurcation of localized states, appearing as large amplitude peaks nucleating over a pattern of lower amplitude. Localized states are pinned over a lattice spontaneously ...

      Ferré, Michel A.; Clerc Gavilán, Marcel; Coulibally, Saliya; Rojas, René G.; Tlidi, Mustapha (Springer, 2017)
      Driven damped coupled oscillators exhibit complex spatiotemporal dynamics. An archetype model is the driven damped sine-Gordon equation, which can describe several physical systems such as coupled pendula, extended Josephson ...
