Einstein's theory of general relativity states that clocks at different gravitational potentials tick
at different rates relative to lab coordinates—an effect known as the gravitational redshift. As …

MAGIS-100 is a next-generation quantum sensor under construction at Fermilab that aims to
explore fundamental physics with atom interferometry over a 100 m baseline. This novel …

We demonstrate a cavity-based solution to scale up experiments with ultracold atoms in
optical lattices by an order of magnitude over state-of-the-art free-space lattices. Our two …

We present a detailed investigation of the ultranarrow magnetic-quadrupole S 0 1-P 2 3
transition in neutral strontium and show how it can be made accessible for quantum …

Collective couplings of atomic dipoles to a shared electromagnetic environment produce a
wide range of many-body phenomena. We report on the direct observation of resonant …

We report a measurement of the radiative lifetime of the F 7/2 2 level of Yb+ 171 that is
coupled to the S 1/2 2 ground state via an electric octupole transition. The radiative lifetime …

We experimentally demonstrate an optical bistability between two hyperfine ground states of
trapped, cold atoms, using a single mode of an optical resonator in the collective strong …

Atom interferometers measure quantum interference patterns in the wave functions of cold
atoms that follow superpositions of different space-time trajectories. These can be sensitive …

We demonstrate continuous loading of strontium atoms into a high finesse ring cavity and
observe continuous strong collective coupling in the form of a vacuum Rabi splitting …

In this paper, we theoretically calculate the natural lifetime of the 5 s 5 p P 0 o 3 state of the
Sr 87 atom and evaluate the effect of an external magnetic field on the lifetimes of Zeeman …
