Correlations of strongly attractive few-fermion systems — •Philipp M. Preiss, Vincent Klinkhamer, Ralf Klemt, Andrea Bergschneider, Jan Hendrik Becher, Gerhard Zürn, and Selim Jochim — Physikalisches Institut, Universität Heidelberg

Strongly coupled quantum systems are characterized by the correlations between their constituents. We prepare systems with strong attractive interactions containing few 6Li atoms in an optical microtrap. We release the atoms from the trap and measure the positions of the atoms with a spin-resolved single-atom sensitive imaging method after time-of-flight. From these positions, we construct the two-body correlation functions.

Our measurements are ideally suited to study the effects of interactions and quantum statistics in few-particle systems. The measured correlation functions can give access to the microscopic properties of fermionic quantum states and can be used to explore the few-body limit of hydrodynamics or to detect pairing phenomena in the BEC-BCS crossover.
