We study the electron dynamics in atoms and clusters triggered by light carrying orbital angular momentum (or twisted light). It is shown that charge currents can be generated [1] in the system that may be utilized as a source for localized magnetic pulses. For a sizable current it is advantageous to have the system’s size on the scale of the waist size of the laser. Hence, we are investigating the electron dynamics in metal clusters under the action of twisted light with analytical and numerical methods as we developed and presented in [1, 2].
