We report on the observation of the phase dynamics of interacting one-dimensional ultracold bosonic gases with two internal degrees of freedom. By controlling the non-linear atomic interactions close to a Feshbach resonance ...

We propose a method for controllable generation of non-local entangled pairs using spinor atoms loaded in an optical superlattice. Our scheme iteratively increases the distance between entangled atoms by controlling the ...

We study the problem of rapid change of the interaction parameter (quench) in a many-body lowdimensional system. It is shown that, measuring the correlation functions after the quench, the information about a spectrum of ...
