Ultra-cold atoms systems used as quantum simulators offer an alternative way to simulate many-body systemsbehaviour in condensed matter. Indeed, we can create artifcial matter with optical lattices : the stationnarywave reproduces the potential wells in the crystalline structure. Moreover, the big advantage of using coldatoms is that the parameters of the simulated crystal can be well controlled so that we can understand theelectrical and magnetism properties of the condensed matter such as conductivity, ferromagnetism ...Thecommon approach for generating optical lattices is interfering two laser beams in one dimension. And in the newongoing project, we are going to produce lattices by irradiating a nanostructure gold layer, which can realizesub-wavelength optical lattices due to the surface plasmon resonance and Casimir-Polder effects.< Réduire
