Phase effects in double ionization by strong short pulses

Graphical abstract: Double ionization of helium-like atoms by strong single cycle pulses in reduced dimensionality quantum model. Influence of phase relation between the carrier wave and the envelope of the pulse on the total ionization yield, ion and electron momentum distributions is discussed. - Abstract: We consider double ionization induced by strong single cycle pulses within quantum calculations of a reduced dimensionality model. Changes in the phase relation between the wave and the envelope affect the total ionization yield as well as the characteristics in the distribution of the outgoing momenta.
