    • Chaos and coherence in the conservative three-mode decay interaction 

      Frichembruder, Marcos; Pakter, Renato; Gerhardt, Gunther Johannes Lewczuk; Rizzato, Felipe Barbedo (2000) [Artigo de periódico]
      In this work we analyze the influence of chaos on the coherence of the mismatched three-wave interaction. Chaos starts to play a decisive role in the problem when adiabatic approximations leading to an integrable model for ...

    • Coherence–incoherence transition in nonlinear wave interactions 

      Frichembruder, Marcos; Pakter, Renato; Rizzato, Felipe Barbedo (2005) [Artigo de periódico]
      In this paper we analyze the transition from coherent to incoherent wave dynamics in a broad-band triplet interaction, where, in contrast to previous models, wave vector selection rules are imposed on the nonlinear terms ...

    • Microemulsion model with oil-water anisotropy 

      Barbosa, Marcia Cristina Bernardes; Frichembruder, Marcos (1996) [Artigo de periódico]
      We consider a spin model for applications to oil-water-amphiphilic-surfactant mixtures near the region where those phases coexist. We analyze this model assuming that oil and water molecules cannot be treated symmetrically, ...
