In a combined experimental and theoretical study on ultrafast excitation of atoms in intense short pulse
laser fields scientists of the Max Born Institute succeeded to show that the prevailing and seemingly disparate intuitive pictures usually used to describe interaction of atoms with intense laser fields can be ascribed to a single nonlinear process.
