Dialing in the Temperature Needed for Precise Nuclear Timekeeping

A thorium-doped calcium fluoride crystal's temperature is continually monitored while a VUV frequency comb is used to directly resolve individual quantum states of the nuclear transition.

Using Frequency Combs to Detect Molecules in Your Breath

An artist's depiction of the frequency comb's molecular detection in vapor

Sneaky Clocks: Uncovering Einstein’s Relativity in an Interacting Atomic Playground

An optical lattice clock)embedded in the curved spacetime formed by the earth’s gravity. Dynamical interplay between photon-mediated interactions and gravitational redshift can lead to entanglement generation and frequency synchronization dynamics.

Quantum Billiard Balls: Digging Deeper into Light-Assisted Atomic Collisions

Exploiting the hyperfine structure in repulsive light-assisted collisions (LAC) on a 87-Rubidium atom pair in an optical tweezer.

Tracking Magnetic Field Directions Using Tiny Atomic Compasses

Cells with around 100 billion rubidium atoms are exposed to microwave signals, which help to determine the atoms' magnetic fields
