    • Additive Noise Induces Front Propagation 

      Clerc Gavilán, Marcel; Falcón Beas, Claudio; Tirapegui Zurbano, Enrique (2005-04-15)
      The effect of additive noise on a static front that connects a stable homogeneous state with an also stable but spatially periodic state is studied. Numerical simulations show that noise induces front propagation. The ...

      León, Alejandro O.; Laroze, David; Clerc Gavilán, Marcel; Cabañas, Ana M. (Elsevier, 2017)
      Nanomagnets driven with uniform electric currents exhibit a wide variety of spatial textures. In the present work, we investigate alternating superlattice states in nanomagnets, which are spatially periodic textures composed ...
    • Analytical studies of fronts, colonies, and patterns: Combination of the Allee effect and nonlocal competition interactions 

      Clerc Gavilán, Marcel; Escaff, D.; Kenkre, V. M. (American Physical Society, 2010)

    • Asymmetric counter propagation of domain walls 

      Andrade Silva, I.; Clerc Gavilán, Marcel; Odent, V. (Elsevier, 2016)
      Far from equilibrium systems show different states and domain walls between them. These walls, depending on the type of connected equilibria, exhibit a rich spatiotemporal dynamics. Here, we investigate the asymmetrical ...
    • Asymmetric counterpropagating fronts without flow 

      Andrade Silva, I.; Clerc Gavilán, Marcel; Odent, V. (American Physical Society, 2015)
      Out-of-equilibrium systems exhibit domain walls between different states. These walls, depending on the type of connected states, can display rich spatiotemporal dynamics. In this Rapid Communication, we investigate the ...
    • Berry Phase of Light under Bragg Reflection by Chiral Liquid-Crystal Media 

      Barboza, Raouf; Bortolozzo, Umberto; Clerc Gavilán, Marcel; Residori, Stefania (Amer Chemical Society, 2016)
      A Berry phase is revealed for circularly polarized light when it is Bragg reflected by a chiral liquid-crystal medium of the same handedness. By using a chiral nematic layer we demonstrate that if the input plane of the ...
    • Bubbles Interactions in the Cahn-Hilliard Equation 

      Calisto, H.; Clerc Gavilán, Marcel; Rojas, R.; Tirapegui Zurbano, Enrique (2000-10-30)
      We study the dynamics of bubbles in the one dimensional Cahn-Hilliard equation. For a gas of diluted bubbles we find ordinary differential equations describing their interaction which permits us to describe the ulterior ...
    • Can non-propagating hydrodynamic solitons be forced to move? 

      Gordillo, L.; Sauma, T.; Zárate, Y.; Espinoza, I.; Clerc Gavilán, Marcel; Mujica Fernández, Nicolás (Springer, 2011-03)
      Development of technologies based on localized states depends on our ability to manipulate and control these nonlinear structures. In order to achieve this, the interactions between localized states and control tools should ...
    • Chaotic patterns and localized states in spin valves 

      Cabanas, Ana M.; Clerc Gavilán, Marcel; Laroze, David; Leon, Alejandro O. (Elsevier B.V., 2019)
      © 2019 Elsevier B.V. Driven nano-magnets have attracted increasing attention due to their potential applications and complex dynamical behavior. Spin valves are possibly the most studied driven nano-magnets because applied ...
    • Characterization of spatiotemporal chaos in a Kerr optical frequency comb and in all fiber cavities 

      Liu, Z.; Ouali, M.; Coulibaly, S.; Clerc Gavilán, Marcel; Taki, M.; Tlidi, M. (OSA - The Optical Society, 2017)
      Complex spatiotemporal dynamics have been a subject of recent experimental investigations in optical frequency comb microresonators and in driven fiber cavities with Kerr-type media. We show that this complex behavior has ...
    • Characterization of the vortex-pair interaction law and nonlinear mobility effects 

      Barboza, R.; Sauma, T.; Bortolozzo, U.; Assanto, G.; Clerc Gavilán, Marcel; Residori, S. (2013)
      Employing nematic liquid crystals in a homeotropic cell with a photosensitive wall, dissipative vortex pairs are selectively induced by external illumination and the interaction law is characterized for pairs of ...
