Measuring nonlocal three-body spatial correlations with Rydberg trimers in ultracold quantum gases

Abstract
We measure nonlocal third-order spatial correlations in non-degenerate ultracold gases of bosonic (Sr) and spin-polarized fermionic (Sr) strontium through studies of the formation rates for ultralong-range trimer Rydberg molecules. The trimer production rate is observed to be very sensitive to the effects of quantum statistics with a strong enhancement of up to a factor of six (3!) in the case of bosonic Sr due to bunching, and a marked reduction for spin-polarized fermionic Sr due to anti-bunching. The experimental results are compared to theoretical predictions and good agreement is observed. The present approach opens the way to {\it{in situ}} studies of higher-order nonlocal spatial correlations in a wide array of ultracold atomic-gas systems.
