By probing the optical Stark shifts induced by a few-cycle laser field using isolated attosecond pulses in a transient absorption scheme, we uncover a sub-cycle-laser-induced AC Stark shift in excited states of the helium atom.

Effects of static electric and magnetic fields on the differential ac Stark shifts for microwave transitions in ultracold bosonic ${}^{87}$Rb${}^{133}$Cs molecules are studied experimentally. The ac Stark effect is greatly simplified by applying a dc electric field in addition to the magnetic field.

We demonstrate spatially resolved control of fictitious magnetic fields generated by an optically induced ac-Stark shift as a versatile tool to efficiently prepare complex spin patterns in cold atomic ensemble.
