Quantum simulation: Choose your own interaction

Quantum many-body physics can now be studied experimentally using a variety of methods from atomic and optical physics, such as ultracold atoms, chains of trapped ions or superconducting circuits. The ultimate goal in this field, known as quantum simulation, is to realize well-controlled model systems in regimes that are difficult to understand through analytical and numerical approaches. Typically, this is the case for strongly interacting systems, and consequently the engineering of interactions is at the heart of quantum simulation
