    • Chimera states in a Duffing oscillators chain coupled to nearest neighbors 
      Clerc Gavilán, Marcel; Coulibaly, Saliya; Ferré, Michelle; Rojas, Rene (American Institute of Physics Inc., 2018)
      Coupled nonlinear oscillators can present complex spatiotemporal behaviors. Here, we report the coexistence of coherent and incoherent domains, called chimera states, in an array of identical Duffing oscillators coupled ...
    • Chimera-like states in an array of coupled-waveguide resonators 
      Clerc Gavilán, Marcel; Ferre, M. A.; Coulibaly, S.; Rojas, R. G.; Tlidi, M. (Optical Society of America, 2017)
      We consider coupled-waveguide resonators subject to optical injection. The dynamics of this simple device are described by the discrete Lugiato-Lefever equation. We show that chimera-like states can be stabilized, thanks ...
    • Chimera-type states induced by local coupling 
      Clerc Gavilán, Marcel; Coulibaly, Saliya; Ferré, M. A.; García Ñustes, M. A.; Rojas, R. G. (Amer Physical Soc, 2016)
      Coupled oscillators can exhibit complex self-organization behavior such as phase turbulence, spatiotemporal intermittency, and chimera states. The latter corresponds to a coexistence of coherent and incoherent states ...
    • Effects of translational coupling on dissipative localized states 
      Campo, F. del; Haudin, F.; Rojas, R. G.; Bortolozzo, Umberto; Clerc Gavilán, Marcel; Residori, S. (2012)
      Nonequilibrium localized states under the influence of translational coupling are studied experimentally and theoretically. We show that localized structures are deformed and advected in the direction of the coupling, ...
    • Front propagation into an unstable state in a forced medium: Experiments and theory 
      Alfaro Bittner, K.; Castillo-Pinto, C.; Clerc Gavilán, Marcel; González Cortés, Gregorio; Rojas, R.; Wilson, M. (American Physical Society, 2018)
      Spatially forced systems can exhibit coexistence and a rich interface dynamics between manipulable states. We show here how the propagation speed of a front into an unstable state can be modified through periodic space ...
    • Front propagation steered by a high-wavenumber modulation: Theory and experiments 
      Alfaro Bittner, K.; Castillo Pinto, C.; Clerc Gavilán, Marcel; González-Cortés, G.; Jara Schulz, G.; Rojas, R. G. (American Institute of Physics, 2020)
      Homogeneously driven dynamical systems exhibit multistability. Depending on the initial conditions, fronts present a rich dynamical behavior between equilibria. Qualitatively, this phenomenology is persistent under spatially ...
    • Modeling the Lateral Wet Oxidation of AlxGa1-xAs into Arbitrary Mesa Geometries 
      Alfaro Bittner, K.; Rojas, R. G.; Lafleur, G.; Calvez, S.; Almuneau, G.; Clerc Gavilán, Marcel; Barbay, S. (American Physical Society, 2019)
      We report experimental and theoretical results on the lateral wet oxidation of bidimensional thin aluminum-rich layers into AlOx. We introduce a reaction-diffusion model of oxidation front propagation that includes effects ...
    • pi - kink propagation in the damped Frenkel Kontorova model 
      Alfaro Bittner, K.; Clerc Gavilán, Marcel; García Nustes, M. A.; Rojas, R. G. (EPL Association European Physical Society, 2017)
      Coupled dissipative nonlinear oscillators exhibit complex spatiotemporal dynamics. Frenkel-Kontorova is a prototype model of coupled nonlinear oscillators, which exhibits coexistence between stable and unstable state. This ...
