Strongly correlated one-dimensional Fermi gases: when is 1D truly 1D
Low-dimensional quantum many-body systems are characterized by physical properties that are vastly different from their three-dimensional counterparts and this dramatic breakdown of the paradigms governing 3D systems leads to novel physical phenomena, from the peculiar topological properties characterizing 2D ensembles of particles, to the integrability of 1D systems that precludes their relaxation towards thermal equilibrium. Thanks to the versatility of atomic physics manipulation techniques, it is possible to simulate experimentally lower- dimensional systems using ultracold atoms. In this talk I will present recent results obtained at ENS on the observation and the characterization of singly resolved one-dimensional quantum gases and I will discuss the competition between interactions and dimensionality in strongly correlated confined systems.
