Abstract / Description: 

What can we learn about a many-body system when we measure every constituent particle? Current experiments with ultracold atoms provide snapshots of many-body states with single particle resolution. This calls for new approaches to studying quantum many-body systems with a focus on analyzing patterns and using machine learning techniques. I will present a recent application of this method to study magnetic polarons in antiferromagnetic Mott insulators. Results indicate that magnetic polarons can be accurately described as spinon-chargon pairs bound by geometric strings, in close analogy to mesons in QCD as quark-antiquark bound pairs.
