Quantum correlations play a key role across many areas of physics. They drive quantum phase transitions, govern the structure of the periodic table and nuclear chart, are used to classify the complexity of certain numerical problems, and form the heart of quantum enhanced metrology. Atomic few-body systems have historically played a pivotal role in the understanding of quantum correlations. Over the past decades, ever more sophisticated preparation and detection schemes for ultracold atoms have been developed. As a consequence, ultracold few-atom systems have emerged as prototype systems with which to study the build-up of correlations with unprecedented control as a function of the interaction strength and the number of particles. This talk will summarize our recent work on spatial and spin correlations of few-body systems that are characterized by a large two-body s-wave scattering length.
