Interfering optical vortices generate centrifugal traps and shot ramp for neutral atoms. The phenomena rely on the highly non‐linear dynamics of the atomic charge in high‐intensity laser fields that carries orbital angular momenta. The interference pattern of optical vortices enables controllable sub‐optical wavelength traps with a structure tuneable by the optical vortices topological charges. A detuning between the frequencies of the interfering pulses set, the trapped atoms in controlled rotation. (Image: D. Schulze et al.; article number 1600379 in this issue).
