RESUMO:

We studied the Gouy phase for the non-resonant and resonant harmonic
evolution of a correlated Gaussian state, considering the ground state of a harmonic
oscillator with frequency ω0 as the initial state of a particle, which is correlated in
position and momentum, encoded by the parameter γ. We also considered the evolution
of the initial state in a harmonic potential with frequency ω and calculated the Gouy
phase, where we observed that a Gouy phase term always exists whenever the initial
state is not an eigenstate of the Hamiltonian. Finally, we analyzed the Gouy phase in the
regimes of fast and slow matter-wave diffraction.
