Abstract:

We describe two possible configurations for optical lattice clocks; a one-dimensional (1D) lattice loaded with spin-polarized fermions and a three-dimensional (3D) lattice loaded with bosons. We realized these lattice clocks with fermionic ⁸⁷Sr and bosonic ⁸⁸Sr atoms and performed an optical frequency comparison between the two. The future prospects of a cryogenic Sr lattice clock and a blue-detuned lattice clock are also discussed.
