    • 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 ...
    • Dissipative structures induced by photoisomerization in a dye-doped nematic liquid crystal layer 

      Andrade-Silva, Ignacio; Bortolozzo, Umberto; Castillo Pinto, Camila; Clerc, Marcel; González-Cortés, Gregorio; Residori, S.; Wilson, Mario (Royal Society Publishing, 2018)
      Order–disorder phase transitions driven by temperature or light in soft matter materials exhibit complex dissipative structures. Here, we investigate the spatio-temporal phenomena induced by light in a dye-doped nematic ...
    • 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 ...
    • Optical vortex induction via light-matter interaction in liquid-crystal media 

      Barboza, R.; Bortolozzo, U.; Clerc Gavilán, Marcel; Residori, Stefania; Vidal Henríquez, Estefanía (Optical Soc Amer., 2015)
      Optical vortices are attracting much attention because of their applications in various fields of optical processing, communications, enhanced imaging systems, and bio-inspired devices. Different methods to generate optical ...
