• Chiral bosons through linear constraints 

      Girotti, Horacio Oscar; Gomes, Marcelo; Rivelles, Victor O. (1992) [Artigo de periódico]
      We study in detail the quantization of a model which apparently describes chiral bosons. The model is based on the idea that the chiral condition could be implemented through a linear constraint. We show that the space of ...
    • Waterlike hierarchy of anomalies in continuous spherical shouldered potential 

      Oliveira, Alan Barros de; Franzese, Giancarlo; Netz, Paulo Augusto; Barbosa, Marcia Cristina Bernardes (2008) [Artigo de periódico]
      We investigate by molecular dynamics simulations a continuous isotropic core-softened potential with attractive well in three dimensions, introduced by Franzese [J. Mol. Liq. 136, 267 (2007)], that displays liquid-liquid ...
