    • The S=1 underscreened anderson lattice model for uranium compounds 

      Thomas, Christopher; Simões, Acirete Souza da Rosa; Iglesias, Jose Roberto; Lacroix, Claudine; Perkins, Natalia B.; Coqblin, Bernard (2011) [Artigo de periódico]
      Magnetic properties of uranium and neptunium compounds showing coexistence of the Kondo e®ect and ferromagnetic order are investigated within the degenerate Anderson Lattice Hamiltonian, describing a 5f2 electronic ...

    • Two-cell correlations in biological tissues 

      Mombach, Jose Carlos Merino; Almeida, Rita Maria Cunha de; Iglesias, Jose Roberto (1993) [Artigo de periódico]
      We present two-cell correlation functions ml(n), which give the average number of t-sided cells adjacent to n-sided ones, obtained experimentally from vegetable tissues and through a numerical simulation that includes ...

    • Underscreened Kondo lattice model applied to heavy fermion uranium compounds 

      Perkins, Natalia B.; Núñez-Regueiro, M.D.; Coqblin, Bernard; Iglesias, Jose Roberto (2007) [Artigo de periódico]
      We present theoretical results for the underscreened Kondo lattice model with localized S=1 spins coupled to a conduction band through a Kondo coupling, JK, and interacting among them ferromagnetically. We use a fermionic ...
