Abstract: Entanglement is fundamental to our understanding of many-body quantum systems, and it is a key concept underlying a plethora of phenomena such as topological properties.  A powerful theoretical tool to characterize entanglement in a quantum many-body system is the so-called entanglement spectrum, which characterizes the statistical properties of a (reduced) quantum state. We build on versatile tools to control and manipulate cold atoms available in current experiments, and we develop protocols to measure entanglement entropies and the largest eigenvalues of the entanglement spectrum.
