Simulate Ion Traps with Neutral Atoms:. Stark Atom Chip and Optical Lattice Clock

Employing engineered electric fields, we demonstrate two coherence-preserving atom traps for precision measurements with neutral atoms. (1) A surface Stark trap has been developed to manipulate scalar atoms near solid surfaces. (2) An optical lattice clock has been realized for ⁸⁷Sr atoms and its absolute frequency was measured.
