    • 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 ...
    • Colorimetry characterization of molecular reorientation transition in thin nematic cells 
      Morel, Jean Paul; Bortolozzo, Umberto; Clerc Gavilán, Marcel; Jullien, A.; Residori, S. (American Institute of Physics, 2020)
      The characterization of equilibria and their transition is fundamental in dynamic systems. Experimentally, the characterization of transitions is complex due to time scales separation, the effect of thermal fluctuations, ...
    • Dissipative structures induced by photoisomerization in a dye-doped nematic liquid crystal layer 
      Andrade Silva, Ignacio Javier; Bortolozzo, Umberto; Castillo Pinto, Camila; Clerc Gavilán, 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 ...
    • 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, ...
    • 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, ...
