    • 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 ...
    • 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, ...
    • 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 ...
