Faraday patterns in interference experiments with one dimensional gases of ultracold atoms

POSTER

Abstract

We analyze a quantum analogue of the Faraday instability in one dimensional ultracold gases. Temporal periodic modulation of the interaction strength parametrically excites collective modes and gives rise to standing wave patterns in interference experiments. We discuss both bosonic and fermionic systems and demonstrate that such experiments can be used to probe spin charge separation.
