  • A T-matrix many-particle theory for coherently coupled superlattice optics 
    Schmielau, T.; Pereira Jr., M.F.; Henneberger, K. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2004)
    The high- order Coulomb correlations described by T-matrix diagrams in both carrier occupation and polarization functions are studied here with a Keldysh- Green’s Functions formalism. Numerical applications for low dimensional ...
  • Many-body theory of all-optical quantum well logic gates 
    Pereira Jr., M.F.; Prado, M.; Sampaio, R. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2002)
    A many-body theory, based on the solutions of generalized semiconductor Maxwell-Bloch equations for coupled-band multiple quantum wells is applied to the description of the optical non linearities responsible for the ...
  • Many particle and bandstructure effects in intersubband quantum well optics 
    Pereira Jr., M.F. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2003)
    In this paper, intersubband optical absorption spectra are computed from an optical susceptibility derived from the many-body formalism. The theory is valid for both non-equilibrium and equilibrium conditions. Numerical ...
  • Photon Green’s functions theory for Coulomb correlated quantum well lasers 
    Pereira Jr., M.F. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2004)
    A photon Green’s function theory is used to incorporate Bethe-Salpeter-like many body corrections in the computations of output spectra of semiconductor quantum well lasers. Coulomb, quantum-confinement, multiple valence ...
