Magic Wavelengths for Optical-Lattice Based Cs and Rb Active Clocks
Atoms, 2020 Active clocks could provide better stabilities during initial stages of measurements over passive clocks, in which stabilities become saturated only after long-term measurements.

Optical Lattice Induced Light Shifts in an Yb Atomic Clock [PDF]
, 2008 We present an experimental study of the lattice induced light shifts on the 1S_0-3P_0 optical clock transition (v_clock~518 THz) in neutral ytterbium. The ``magic'' frequency, v_magic, for the 174Yb isotope was determined to be 394 799 475(35)MHz, which ...

An Atomic-Array Optical Clock with Single-Atom Readout
Physical Review X, 2019 Currently, the most accurate and stable clocks use optical interrogation of either a single ion or an ensemble of neutral atoms confined in an optical lattice.

Integrating planar photonics for multi-beam generation and atomic clock packaging on chip
Light: Science & Applications, 2023 The commercialization of atomic technologies requires replacing laboratory-scale laser setups with compact and manufacturable optical platforms. Complex arrangements of free-space beams can be generated on chip through a combination of integrated ...

Demonstration of a time scale with the 87Sr optical lattice clock at NTSC
AIP Advances, 2023 Optical clocks have been applied to the generation of time scales since they provide superb uncertainty and instability in recent years. This paper presents the simulations about the impact of the optical clock’s operational strategies on the performance

Collisional losses, decoherence, and frequency shifts in optical lattice clocks with bosons
, 2009 We have quantified collisional losses, decoherence and the collision shift in a one-dimensional optical lattice clock with bosonic 88Sr. The lattice clock is referenced to the highly forbidden transition 1S0 - 3P0 at 698 nm, which becomes weakly allowed ...

Cancellation of collisional frequency shifts in optical lattice clocks with Rabi spectroscopy
New Journal of Physics, 2016 We analyze both the s- and p -wave collision induced frequency shifts and propose an over- π pulse scheme to cancel the shifts in optical lattice clocks interrogated by a Rabi pulse.
