Colloquium: Physics of optical lattice clocks [PDF]

open access: yesReviews of Modern Physics, 2010
Recently invented and demonstrated, optical lattice clocks hold great promise for improving the precision of modern timekeeping. These clocks aim at the 10^-18 fractional accuracy, which translates into a clock that would neither lose or gain a fraction ...

Continuously trapped matter-wave interferometry in magic Floquet-Bloch band structures [PDF]

open access: yesNature Communications
Trapped matter-wave interferometry offers the promise of compact high-precision local force sensing. However, noise in the trap itself can introduce new systematic errors which are absent in traditional free-fall interferometers.

Lattice-induced non-adiabatic frequency shifts in optical lattice clocks [PDF]

open access: yesPhysical Review A, 2010
We consider the frequency shift in optical lattice clocks which arises from the coupling of the electronic motion to the atomic motion within the lattice.

Nuclear Spin Effects in Optical Lattice Clocks [PDF]

open access: yesPhysical Review A, 2007
We present a detailed experimental and theoretical study of the effect of nuclear spin on the performance of optical lattice clocks. With a state-mixing theory including spin-orbit and hyperfine interactions, we describe the origin of the $^1S_0$-$^3P_0$

A noise-immune cavity-assisted non-destructive detection for an optical lattice clock in the quantum regime

open access: yesNew Journal of Physics, 2017
We present and implement a non-destructive detection scheme for the transition probability readout of an optical lattice clock. The scheme relies on a differential heterodyne measurement of the dispersive properties of lattice-trapped atoms enhanced by a

Symmetry-Protected Topological Optical Lattice Clock

open access: yesPRX Quantum
We theoretically propose a tunable implementation of symmetry-protected topological phases of matter in a synthetic superlattice, taking advantage of the long coherence time and exquisite spectral resolutions offered by gravity-tilted optical lattice ...

Toward a quantum-enhanced strontium optical lattice clock at INRIM [PDF]

open access: yesEPJ Web of Conferences, 2020
The new strontium atomic clock at INRIM seeks to establish a new frontier in quantum measurement by joining state-of-the-art optical lattice clocks and the quantized electromagnetic field provided by a cavity QED setup.

Blackbody radiation shift in strontium lattice clocks revisited

open access: yesPhysical Review Research, 2021
We reevaluate the blackbody radiation (BBR) induced ac-Stark shift of the strontium clock transition (5s5p)^{3}P_{0}-(5s^{2})^{1}S_{0} at 698nm used as reference in optical lattice clocks and as secondary representation of the SI unit “second.” At room ...

The development of active optical clock

open access: yesAAPPS Bulletin, 2023
The atomic clocks, whether operating at optical or microwave region, can be divided into two categories according to their working mode, namely the passive clocks and active clocks.
