    • Nonintegrable dynamics of the triplet-triplet spatiotemporal interaction 

      Lopes, Sergio Roberto; Rizzato, Felipe Barbedo (1999) [Artigo de periódico]
      In this paper we examine the coupling of two wave triplets sharing two common modes. The analysis is performed in the solitonic sector of the parameter space where uncoupled solutions departing from linearly unstable ...

    • Nonintegrable interaction of ion acoustic and electromagnetic waves in a plasma 

      Rizzato, Felipe Barbedo; Lopes, Sergio Roberto; Chian, Abraham Chian-Long (1997) [Artigo de periódico]
      In this paper we reexamine the one-dimensional interaction of electromagnetic and ion acoustic waves in a plasma. Our model is similar to one solved by Rao et al. [Phys. Fluids 26, 2488 (1983)] under a number of analytical ...
