    • Probing the reciprocal lattice associated with a triangular slit to determine the orbital angular momentum for a photon 

      Soares, Willamys Cristiano; Moura, André de Lima; Canabarro, Askery Alexandre; Lima, Emerson de; Andrade, Jose Henrique Araujo Lopes de; Fonseca, Eduardo Jorge da Silva; Felisberto, M. L.; Bernardo, Bertulio de Lima; Hickmann, Jandir Miguel; Châvez-Cerda, Sabino C. (2020) [Artigo de periódico]
      The orbital angular momentum conservation of light reveals different diffraction patterns univocally dependent on the topological charge of the incident light beam when passing through a triangular aperture. It is demonstrated ...

    • Unveiling square and triangular optical lattices : a comparative study 

      Silva, Juarez Gomes da; Jesus-Silva, Alcenísio J.; Alencar, Marcio André Rodrigues Cavalcanti de; Hickmann, Jandir Miguel; Fonseca, Eduardo Jorge da Silva (2014) [Artigo de periódico]
      We study square and triangular optical lattice formation using a diffraction technique with light-possessing orbital angular momentum (OAM). We demonstrate that it is possible to use Fraunhofer diffraction of light by a ...

    • Very low mass stellar and substellar companions to solar-like stars from MARVELS. II. A short-period companios orbiting an F star with evidence of a stellar tertiary and significant mutual inclination

      We report the discovery via radial velocity (RV) measurements of a short-period (P = 2.430420±0.000006 days) companion to the F-type main-sequence star TYC 2930-00872-1. A long-term trend in the RV data also suggests the ...
