What is a clockwork mechanism?

A preprint version of the article is available at arXiv. The clockwork is a mechanism for generating light particles with exponentially suppressed interactions in theories which contain no small parameters at the fundamental level. We develop a general description of the clockwork mechanism valid for scalars, fermions, gauge bosons, and gravitons.

What is a geared or clockwork mechanism?

Geared or clockwork mechanisms have many time-related uses beyond straightforward time-telling. In science, orreries offer models of the solar system;

Are Transportable Optical clocks better than laboratory-based clocks?

Emerging clock applications such as relativistic geodesy require transportable optical clocks, which currently have poorer stabilities and accuracies than those of laboratory-based clocks.

What was the linewidth of the clock laser used?

Taking advantage of an 8-mHz linewidth clock laser, the frequency gradient due to the gravitational redshift across a single millimeter-scale atom ensemble was recently observed using Rabi spectroscopy of 87 Sr without the use of a blinding offset.

What are some ways to use atomic clocks in physics research?

Atomic clocks have been used in various physics research, such as hunting for topological dark matter (Derevianko & Pospelov, 2014), detecting gravitational waves (Kolkowitz et al., 2016), and searching for new physics (Safronova et al., 2018).

Why do laboratory-based optical clocks use bulky and immobile reference cavities?

State-of-the-art laboratory-based optical clocks often use bulky and immobile reference cavities with second-scale coherence times to achieve lower levels of clock instability and to aid in rapid systematic evaluation, limiting deployment in the field.
