  • Valverde, Juan Segundo; Pazetti, Márcio (2006)
    We propose a SUSY variant of the action for a massless spinning particles via the inclusion of twistor variables. The action is constructed to be invariant under SUSY transformations and -reparametrizations even when an ...
  • Valverde, Juan Segundo; Souza, Sergio Martins de; Santos, Onofre Rojas (2009)
    We study a two-dimensional XXZ-Ising model on a square-hexagon denoted for simplicity by 4–6 lattice with spin 1/2. The phase diagram at zero temperature is discussed, where five states are found, two types of ferrimagnetic ...
