Build Optical Atomic Clocks for Fundamental Physics

Join the NonImaging Optical Design Technical Group and the Optical Cooling and Trapping Technical Group for this exciting webinar featuring Jun Ye from JILA and the University of Colorado at Boulder.

Optical technologies such as frequency-stabilized lasers and laser cooling and trapping of atoms have revolutionized atomic physics and metrology. Scaling up the size of coherent quantum systems advances the frontier of precision measurement, and quantum entanglement is poised to make major impact in the near term. The new generation of optical atomic clocks enabled by modern laser technology and quantum science provide new opportunities to probe fundamental physics and explore emerging quantum phenomena. Recent advances include determination of the gravitational time dilation across a few hundred micrometers and employment of spin entanglement for optical clock comparison.

Subject Matter Level: Intermediate - Assumes basic knowledge of the topic

What You Will Learn:
• The working principles of optical atomic clocks, the most accurate man-made timekeepers ever built, and how they can be used to probe changes in local gravity over millimeter-scale distances.
• The experimental techniques for cooling, trapping and how they can be used to measure time with extremely high accuracy.

Who Should Attend:
• Physicists and engineers interested in how to measure gravity and even test general relativity with benchtop cold atom experiments.
• Scientists interested in the design of the optical setups required to build and control quantum systems with long coherence times.
