We present an experimental study of seeded four-wave mixing (4WM) using a diamond excitation scheme (with states from the 5S1/2,5P1/2,5P3/25S1/2,5P1/2,5P3/2 and 5D3/25D3/2 terms) in a thermal vapour of 87Rb87Rb atoms. We investigate the 4WM spectra u... Read More about Four-wave mixing in a non-degenerate four-level diamond configuration in the hyperfine Paschen–Back regime.

We experimentally demonstrate the generation of heralded bi-chromatic single photons from an atomic collective spin excitation (CSE). The photon arrival times display collective quantum beats, a novel interference effect resulting from the relative m...
