    • 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 ...
    • 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, ...
    • Fronts and localized structures in a liquid-crystal-light-valve with optical feedback 

      Residori, S.; Petrossian, A.; Nagaya, T.; Riera, C. S.; Clerc Gavilán, Marcel (ELSEVIER, 2004-12-01)
      We show that in a liquid-crystal-light-valve with optical feedback the Freedericksz transition displays a subcritical character. Experimentally, we determine the extension of the bistable region and we study the propagation ...
    • Light-matter interaction induces a shadow vortex 

      Barboza, R.; Bortolozzo, U.; Clerc Gavilán, Marcel; Dávila Bonczos, Juan; Kowalczyk, Michal; Residori, S.; Vidal Henríquez, E. (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, ...
    • 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 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 ...
