• Emaranhamento intrínseco em sistemas tipo-Dirac 

      Bittencourt, Victor Augusto Sant Anna Valderramos (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 06/03/2018)
      Dirac equation is supported by a $SU(2) \otimes SU(2)$ group structure, such that its solutions describe two discrete degrees of freedom, intrinsic parity and spin, which in general are entangled. In this work we will ...
    • Existence and multiplicity of solutions for problems involving the Dirac operator 

      Somavilla, Fernanda (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Matemática - PPGM, Câmpus São Carlos, 30/07/2019)
      In this thesis, we study equations that involving the Dirac operator and which have the form $-i \alpha \cdot \nabla u + a \beta u + M(x)u = F_{u}(x,u), em \mathbb{R}^{3},$ where $\alpha = (\alpha_1, \alpha_2, \alpha_3),$ ...
    • Correlações intrínsecas em sistemas tipo-Dirac confinados por um campo magnético constante 

      Silva, Caio Fernando e (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 04/07/2024)
      The Weyl-Wigner formalism in phase space is investigated in the context of Dirac spinors as qubits correlated by continuous degrees of freedom. The extension to relativistic equations connects quantum mechanical phenomena ...
