• Structural properties of nanoscopic ring systems and their optical response 

      Oliveira Neto, Vivaldo Lopes (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 30/03/2016)
      In this thesis, the electronic and structural properties of nanostructured systems were studied aiming to get a realistic model for quantum rings, potentially adaptable for quantum dots. To attain these goals, several ...
    • Estrutura eletrônica de anéis quânticos 

      Oliveira Neto, Vivaldo Lopes (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, , 09/08/2011)
      The nanoscopic structures with ring topology, or quantum rings, have attracted the interest due to their unique rotational symmetry and the possibility of checking fundamental quantum phenomena. Among them, the study of ...
