For a long time exactly solvable models were considered to be mathematical toy models. However, this impression was changed over the past two decades due to advanced quantum engineering of genuine many-body systems using ultracold atoms. In particular, some prototypical exactly solvable Yang–Baxter systems have been successfully realized allowing us to confront elegant and sophisticated exact solutions of these systems with their experimental counterparts. Such new experimental systems provide novel and useable quantum simulators of  unique many-body phenomena with integrability.

In this talk, I will briefly introduce new frontiers in quantum integrability, and  then  show a quantum simulator of Yang-Gaudin model, which remarkably provides a determinant observation of the Luttinger theory of spin-charge separation in the trapped 1D ultracold Fermi gas.
