TLDR
In this article, a single-crystal silicon system that offers a fractional frequency instability of 1 × 10−16 at short timescales and supports a laser linewidth of less than 40 mHz at 1.5 µm is presented.Abstract:
Frequency stabilization in a high-finesse optical cavity is limited fundamentally by thermal-noise-induced cavity length fluctuations. Scientists have now developed a single-crystal silicon system that offers a fractional frequency instability of 1 × 10−16 at short timescales and supports a laser linewidth of less than 40 mHz at 1.5 µm.read more

TL;DR: This work demonstrates a many-atom system that achieves an accuracy of 6.4 × 10−18, which is not only better than a single-ion-based clock, but also reduces the required measurement time by two orders of magnitude.

TL;DR: This work performs a new accuracy evaluation of the JILA Sr clock, reducing many systematic uncertainties that limited previous measurements, such as those in the lattice ac Stark shift, the atoms' thermal environment and the atomic response to room-temperature blackbody radiation.

Photon blockade in an optical cavity with one trapped atom
TL;DR: Observations of photon blockade for the light transmitted by an optical cavity containing one trapped atom, in the regime of strong atom–cavity coupling represent an advance over traditional nonlinear optics and laser physics, into a regime with dynamical processes involving atoms and photons taken one-by-one.
