    • Barboza, Raouf; Bortolozzo, Umberto; Clerc Gavilán, Marcel; Residori, Stefania (Amer Chemical Society, 2016)
      A Berry phase is revealed for circularly polarized light when it is Bragg reflected by a chiral liquid-crystal medium of the same handedness. By using a chiral nematic layer we demonstrate that if the input plane of the ...
    • Zambra, Valeska; Clerc Gavilán, Marcel; Barboza, Raouf; Bortolozzo, Umberto; Residori, Stefania (Amer Physical Soc, 2020)
      Electrically driven nematic liquid crystals layers are ideal contexts for studying the interactions of local topological defects, umbilical defects. In homogeneous samples the number of defects is expected to decrease ...
