Patent Abstract

A method for generating state-dependent lattice potentials for cold includes irradiating of the atoms with a first bichromatic field including a first light wave and a second light wave running in the opposite direction to the first light wave, wherein the first light wave has a first frequency ω and the second light wave has a second frequency ω+Δω; and irradiating the atoms with a second bichromatic field including a first radio or microwave and a second radio or microwave, wherein the first radio or microwave has a third frequency ωMW and the second radio or microwave has a fourth frequency ωMW−Δω.
