126. Towards the next-generation of optical lattice clocks

Andrew Ludlow (National Institute of Standards and Technology)

17/10/2023, 08:30

Molecular, Atomic, Ion and Nuclear Clocks

Invited Oral

We describe recent techniques, strategies, and efforts toward realizing next-generation optical clock uncertainty and stability with the NIST Yb optical lattice clock.

15. Vibrational Molecular Lattice Clocks

Tanya Zelevinsky

17/10/2023, 09:00

Molecular, Atomic, Ion and Nuclear Clocks

Invited Oral

This talk will discuss a vibrational molecular lattice clock based on ultracold strontium dimers, its systematic evaluation at the 14th decimal digit, the current limitations, and paths forward.

118. Developments to improve the stability of optical lattice clocks

Sébastien Bize (LNE-SYRTE, Observatoire de Paris - PSL, CNRS, Sorbonne Université)

17/10/2023, 09:30

Molecular, Atomic, Ion and Nuclear Clocks

Invited Oral

We will present the progress of our Hg optical lattice clock. This work is motivated, in particular, by the low sensitivity of Hg to blackbody radiation and stray electric fields and by the possibility to use ratio between Hg and other optical transitions for fundamental physics and metrology. We re-port on our work done with the 199Hg fermionic isotope to improve uncertainty, stability and...

152. Engineered Hamiltonian for high clock precision and accuracy

Prof. Jun Ye (JILA, National Institute of Standards and Technology and University of Colorado, Boulder)

Molecular, Atomic, Ion and Nuclear Clocks

Invited Oral

Precise quantum state engineering, many-body physics, and innovative laser technology are revolutionizing the performance of atomic clocks and metrology, providing opportunities to explore emerging phenomena and probe fundamental physics. A Wannier-Stark optical lattice configuration highlights such an example. Atom-light and atom-atom interactions in the shallow optical lattice are precisely...
