Rapid progress in theoretical understanding and experimental control of systems of ultracold atoms makes it possible to use these systems to address fundamental problems of quantum many-body theory. In this talk I will review several recent examples, including successful demonstration of the Higgs excitation in a strongly correlated two dimensional superfluid, observation of the prethermolized state in the nearly integrable system, interferometric measurement of the topological order parameter.
