"Quench-Induced Floquet Topologicalﾠp-Wave Superfluids." <i>Physical Review Letters,</i> 113, no. 7 (2014) American Physical Society: https://doi.org/10.1103/PhysRevLett.113.076403.https://hdl.handle.net/1911/94754Ultracold atomic gases in two dimensions tuned close to a p-wave Feshbach resonance were expected to exhibit topological superfluidity, but these were found to be experimentally unstable. We show that one can induce a topological Floquet superfluid if weakly interacting atoms are brought suddenly close (“quenched”) to such a resonance, in the time before the instability kicks in. The resulting superfluid possesses Majorana edge modes, yet differs from a conventional Floquet system as it is not driven externally. Instead, the periodic modulation is self-generated by the dynamics.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
