MOSHINSKY, M.  e  SADURNI, E.. Time dependent problems in relativistic quantum mechanics. Rev. mex. fis. [online]. 2006, vol.52, suppl.4, pp.74-76. ISSN 0035-001X.

The most effective procedure for dealing with time dependent problems is through the Feynman propagator. In this note we indicate the explicit expression for this propagator in relativistic problems using spectral decomposition. We then take as an initial state one of a Dirac oscillator and consider the behaviour of the wave function when the interaction is suddenly supressed.

Palavras-chave : Transient phenomena; propagators; wave functions.
