Ultrastable Optical Clock with Neutral Atoms in an Engineered Light Shift Trap

Does someone can explain that?????

The transition frequency v of atoms exposed to the
lattice electric field of E is described as,

hv = hv^(0)-(1/4) alpha(e,w)E^2-(1/64) gama(e,w)E^4

where v^(0) is the transition frequency between the unperturbed atomic states, alpha(e,w) and gama(e,w) are the difference between the ac polarizabilities and hyperpolarizabilities of the upper and lower states, which in the general case depends both on the light wave frequency w and on the unit polarization vector e.
