No Cavity, No Party: Free-Space Atoms Give Superradiant Transition a Pass

A pencil-shaped ultracold gas of frozen two-level atoms interacting via photon-mediated interactions, with elastic and inelastic components. A continuous laser drive excites the atoms on-resonance. Atoms also spontaneously emit photons into free-space.

Creating a Global Map of Different Physics Laboratory Classes

World map of number of survey responses. Shown on a log scale, each colored country has at least one response; countries in gray have no responses.

Polar Molecules Dance to the Tunes of Microwaves

Pulse sequences for generating two-axis twisting rotate the spins of KRb molecules, transforming the spin exchange interactions.

Moving into a Nuclear Timekeeping Domain

Using an extremely high-powered laser, scientists can excite the thorium-229 nucleus, which is the core of a future nuclear clock.
