Abstract
The magic wavelength for an optical lattice for hydrogen atoms that cancels the lowest order ac Stark shift of the 1S-2S transition is calculated to be 513 nm. The magnitudes of the ac Stark shift ΔE = −119 Hz/(kW/cm[superscript 2]) and the slope dΔE/dν = −2.77 Hz/(GHz kW/cm[superscript 2]) at the magic wavelength suggest that a stable and narrow-line-width trapping laser is necessary to achieve a deep enough optical lattice to confine hydrogen atoms in a way that gives a small enough light shift for the precision spectroscopy of the 1S-2S transition.
