Abstract :
Two "optical lattice clocks", which based on spin-polarized fermionic 87Sr trapped in a one-dimensional optical lattice and on bosonic 88Sr in a three-dimensional lattice, were operated simultaneously. From a beat note between the two optical clocks, stability as well as accuracy of "optical lattice clocks" was evaluated.
