  • Souza, L. A. M.; Drumond, R. C.; Nemes, M. C.; Romero, K. M. Fonseca (Optics Communications, 2012-10-01)
    We analytically exploit the two-mode Gaussian states nonunitary dynamics. We show that in the zero temperature limit, entanglement sudden death (ESD) will always occur for symmetric states (where initial single-mode ...
  • Souza, L. A. M.; Faria, J. G. P.; Nemes, M. C. (Optics Communications, 2014-11-15)
    In this work we use the formalism of chord functions (i.e. characteristic functions) to analytically solve quadratic non-autonomous Hamiltonians coupled to a reservoir composed by an infinity set of oscillators, with ...
