Using high-resolution lasers to test quantum electrodynamics. High-precision laser-based measurements of atomic and molecular structure are benchmarks for our fundamental understanding of matter. This project will undertake state-of-the-art experiments on atomic helium, to test and challenge current theoretical predictions of fundamental quantum-electrodynamic properties for helium and for more complex atoms.
Stealth for atoms: tune-out wavelengths to test quantum electrodynamics. This project aims to measure the tune-out and magic wavelengths for the helium atom to challenge quantum electrodynamics. The project will use a technique to measure the potential confining ultracold atoms which, combined with high accuracy wavelength determination, will enable measurements of unprecedented precision. This project aims to advance fundamental understanding of atomic structure, and yield new insights with pot ....Stealth for atoms: tune-out wavelengths to test quantum electrodynamics.
