Probing Nonlocal Pair Correlations in a Quantum Gas using Ultra-long-range Rydberg Molecules
Abstract
This proposal is to develop photo-excitation of ultra-long-range Rydberg molecules (ULRRMs)as a new tool for probing in situ pair-correlation functions in the intermediate regimebetween short-range and optical-lattice length scales. ULRRMs can be created with verywell defined internuclear spacing, set by the radius of the outer lobe of the Rydberg electronwavefunction. The excitation rate thus serves as a measure of the probability of finding twoparticles in the quantum gas with that defined separation, which is the essence of the nonlocalpair-correlation function g2(R) . During the timeframe of this grant and using ultracoldgases of atomic strontium, we will use this technique to map resonant atomic scatteringstates, correlations arising from quantum statistics, and the wavefunction of a 1D Bose gas.
