Abstract

Abstract: The interaction of a short, few-cycle light pulse and an atom which is prepared initiallyin a superposition of two stationary states is shown to exhibit strong signatures ofatomic coherence. For a given waveform of the laser pulse, appropriate quantum mechanicalrelative phase between the constituents of the initial superposition can increase theionization probability by a factor of three. A similarly strong effect can be observedwhen the waveform of the ionizing pulse is changed. These results allow for intuitiveexplanations, which are in agreement with the numerical integration of the time dependentSchrödinger equation. A detailed analysis shows that the verification our findings isfeasible experimentally. Graphical abstract: [Figure not available: see fulltext.]
