Rydberg electrometry for optical lattice clocks [PDF]
Physical Review A, 2017 Electrometry is performed using Rydberg states to evaluate the quadratic Stark shift of the $5s^2$ $^1\textrm{S}_0-5s5p$ $^3\textrm{P}_0$ clock transition in strontium. By measuring the Stark shift of the highly excited $5s75d\;^1\textrm{D}_2$ state using electromagnetically induced transparency, we characterize the electric field with sufficient ...

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

Symmetry-Protected Topological Optical Lattice Clock
PRX QuantumWe 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]
EPJ 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
Physical 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
AAPPS 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.

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.

Yb optical lattice clock at INRIM [PDF]
EFTF-2010 24th European Frequency and Time Forum, 2010 The Unit of Time in the International Systems of Units is realized at the relative frequency accuracy level of few parts in 10-16 by laser cooled Cesium fountains [1]; since 2003 INRIM has operated a laser cooled Cesium fountain with relative frequency accuracy at the level of 5×10-16 and has contributed with this frequency standard to the generation ...
