We investigate the impact of electron-electron correlation on the ionization dynamics of helium in intense, high-frequency laser fields by solving the time-dependent Schrödinger equation from first principles. Although we observe a decrease in the total ionization yield at high field strengths, the hallmark of atomic stabilization, the repulsion between the(More)
We present a novel scheme for quantum manipulation in ultrafast diatomic molecules. A pump mechanism is used to create a coherent superposition of the D + 2 vibrations. A short, intense, control pulse is applied, after a fractional coherence time, to create selective interferences. A 'chessboard' pattern of states can be realised in which the set of(More)
